Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Significant Accounting Policies and Estimates No material changes have been made to the significant accounting policies of Super Micro Computer, Inc., a corporation incorporated under the laws of Delaware, and its consolidated entities (together, the “Company”), disclosed in Note 1, "Organization and Summary of Significant Accounting Policies," in its Annual Report on Form 10-K, filed on August 27, 2021, for the year ended June 30, 2021. Management's estimates include, as applicable, the anticipated impacts of the coronavirus ("COVID-19") pandemic. Basis of Presentation The unaudited condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements included herein reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the periods presented. The consolidated results of operations for the three months ended September 30, 2021 are not necessarily indicative of the results that may be expected for future quarters or for the fiscal year ending June 30, 2022. Concentration of Supplier Risk Certain materials used by the Company in the manufacturing of its products are available from a limited number of suppliers. Shortages could occur in these materials due to an interruption of supply or increased demand in the industry. One supplier accounted for 20.1% and 22.0% of total purchases for the three months ended September 30, 2021 and 2020, respectively. Purchases from Ablecom, and Compuware, related parties of the Company (see Note 8, "Related Party Transactions") accounted for a combined 9.6% and 9.2% of total cost of sales for the three months ended September 30, 2021 and 2020, respectively. Concentration of Credit Risk Financial instruments which potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, restricted cash, investment in an auction rate security and accounts receivable. No single customer accounted for 10% or more of the net sales for the three months ended September 30, 2021 and 2020. One customer accounted for 11.7% and 13.5% of accounts receivable, net as of September 30, 2021 and June 30, 2021, respectively. Accounting Pronouncements Recently Adopted In December 2019, the FASB issued amended guidance, Simplifying the Accounting for Income Taxes , to remove certain exceptions to the general principles from ASC 740 - Income Taxes, and to improve consistent application of U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The guidance is effective for the Company from July 1, 2021. The adoption of the guidance did not have a material impact on its condensed consolidated financial statements and disclosures. Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued authoritative guidance, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance also establishes (1) a general contract modification principle that entities can apply in other areas that may be affected by reference rate reform and (2) certain elective hedge accounting expedients. The amendment is effective for all entities through December 31, 2022. In January 2021, the FASB issued further guidance on this topic, which clarified the scope and application of the original guidance. LIBOR is used to calculate the interest on borrowings under the Company's 2018 Bank of America Credit Facility and E.SUN Credit Facility. The 2018 Bank of America Credit Facility was amended on June 28, 2021 which provided for a new maturity date of June 28, 2026 and fallback terms related to LIBOR replacement mechanics. As the amendment had changes not related to LIBOR replacement, optional expedients under this guidance cannot be elected. The E.SUN Credit Facility will terminate on July 29, 2022 before the phase out of LIBOR. Therefore, the Company does not expect the adoption of the guidance to have an impact on its consolidated financial statements and disclosures.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Disaggregation of Revenue The Company disaggregates revenue by type of product and by geographical market in order to depict the nature, amount, and timing of revenue and cash flows. Service revenues, which are less than 10%, are not a significant component of total revenue, and are aggregated within the respective categories. The following is a summary of net sales by product type (in thousands): Three Months Ended 2021 2020 Server and storage systems $ 849,856 $ 617,788 Subsystems and accessories 182,874 144,462 Total $ 1,032,730 $ 762,250 Server and storage systems constitute an assembly and integration of subsystems and accessories, and related services. Subsystems and accessories are comprised of server boards, chassis and accessories. International net sales are based on the country and geographic region to which the products were shipped. The following is a summary for the three months ended September 30, 2021 and 2020, of net sales by geographic region (in thousands): Three Months Ended 2021 2020 United States $ 560,948 $ 496,086 Asia 263,086 126,707 Europe 179,694 112,089 Other 29,002 27,368 $ 1,032,730 $ 762,250 Contract Balances Generally, the payment terms of the Company’s offerings range from 30 to 60 days. In certain instances, customers may prepay for products and services in advance of delivery. Receivables relate to the Company’s unconditional right to consideration for performance obligations either partially or fully completed. Contract assets are rights to consideration in exchange for goods or services that the Company has transferred to a customer when such right is conditional on something other than the passage of time. Such contract assets are insignificant to the Company’s condensed consolidated financial statements. Contract liabilities consist of deferred revenue and relate to amounts invoiced to or advance consideration received from customers, which precede the Company’s satisfaction of the associated performance obligation(s). The Company’s deferred revenue primarily results from customer payments received upfront for extended warranties and on-site services because these performance obligations are satisfied over time. Revenue recognized during the three months ended September 30, 2021, which was included in the opening deferred revenue balance as of June 30, 2021 of $202.3 million, was $30.0 million. Deferred revenue increased $13.1 million during the three months ended September 30, 2021 as compared to the fiscal year ended June 30, 2021 mainly due to the increase in non-cancellable non-refundable advance considerations received from customers which precede the Company's satisfaction of the associated performance obligations. Transaction Price Allocated to the Remaining Performance Obligations Remaining performance obligations represent in aggregate the amount of transaction price that has been allocated to performance obligations not delivered, or only partially undelivered, as of the end of the reporting period. The Company applies the exemption to not disclose information about remaining performance obligations that are part of a contract that has an original expected duration of one year or less. These performance obligations generally consist of services, such as on-site services, including integration services and extended warranty services that are contracted for one year or less, and products for which control has not yet been transferred. The value of the transaction price allocated to remaining performance obligations as of September 30, 2021 was $215.4 million . The Company expects to recognize approximately 53% of remaining performance obligations as revenue in the next 12 months, and the remainder thereafter. Capitalized Contract Acquisition Costs and Fulfillment Cost Contract acquisition costs are those incremental costs that the Company incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained. Contract acquisition costs consist primarily of incentive bonuses. Contract acquisition costs are considered incremental and recoverable costs of obtaining and fulfilling a contract with a customer and are therefore capitalizable. The Company applies the practical expedient to expense incentive bonus costs as incurred if the amortization period would be one year or less, generally upon delivery of the associated server and storage systems or components. Where the amortization period of the contract cost would be more than a year, the Company applies judgment in the allocation of the incentive bonus cost asset between hardware and service performance obligations and expenses the cost allocated to the hardware performance obligations upon delivery of associated server and storage systems or components and amortizes the cost allocated to service performance obligations over the period the services are expected to be provided. Contract acquisition costs allocated to service performance obligations that are subject to capitalization are insignificant to the Company’s condensed consolidated financial statements. Contract fulfillment costs consist of costs paid in advance for outsourced services provided by third parties to the extent they are not in the scope of other guidance. Fulfillment costs paid in advance for outsourced services provided by third parties are capitalized and amortized over the period the services are expected to be provided. Such fulfillment costs are insignificant to the Company’s condensed consolidated financial statements.

The Chief Executive Officer’s aggregate cash bonuses of u p to $8.1 million are earned in two tranches. The first 50% is payable if the average closing price for the Company’s common stock equals or exceeds $31.61 for any period of 20 consecutive trading days following the date of the agreement and ending prior to September 30, 2021 and the Chief Executive Officer remains employed with the Company through the date that such common stock price goal is determined to have been achieved. This payment can be reduced at the discretion of the Board to the extent the Company has not made adequate progress in remediating its material weaknesses in its internal control over financial reporting as determined by the Board. The second 50% is payable if the average closing price for the Company’s common stock equals or exceeds $32.99 for any period of 20 consecutive trading days following the date of the agreement and ending prior to June 30, 2022 and the Chief Executive Officer remains employed with the Company through the date that such common stock price goal is achieved. During the fiscal year ended June 30, 2021, the target average closing prices for both tranches were met and the cash payment under the second tranche was made. On September 21, 2021, the Audit Committee of the Board determined and advised the Board as to its view that the Company had made adequate progress in remediating the material weaknesses in its internal control over financial reporting. On September 30, 2021, the Board considered and agreed with this assessment, but also considered the impact of accomplishments of Company employees other than Mr. Liang in achieving this adequate progress. The Board exercised its discretion under the terms of the performance bonuses to reduce the payout for the first tranche from 50% to approximately 25% of $8.1 million, for an aggregate of $2.0 million. The payout of $2.0 million was made subsequent to September 30, 2021. The Company previously expected that the full amount of the first tranche would be paid to its Chief Executive Officer and, accordingly, recorded a liability of $3.6 million related to this tranche on its balance sheet as of June 30, 2021. In light of the Board’s action in September 2021 to reduce the amount of the first tranche payout to $2.0 million, the Company adjusted the amount of this liability on its balance sheet as of September 30, 2021 to $2.0 million and recognized a benefit of $1.6 million in its consolidated statement of operations during the quarter ended September 30, 2021. The (benefit) or expense recognized during the three months ended September 30, 2021 and 2020 was $(1.6) million and $0.1 million, respectively.

Fair Value Disclosures [Abstract]
Fair Value Disclosure	Fair Value Disclosure The financial instruments of the Company measured at fair value on a recurring basis are included in cash equivalents, other assets and accrued liabilities. The Company classifies its financial instruments, except for its investment in an auction rate security, within Level 1 or Level 2 in the fair value hierarchy because the Company uses quoted prices in active markets or alternative pricing sources and models using market observable inputs to determine their fair value. The Company’s investment in an auction rate security is classified within Level 3 of the fair value hierarchy as the determination of its fair value was not based on observable inputs as of September 30, 2021 and June 30, 2021. The Company is using the discounted cash flow method to estimate the fair value of the auction rate security at each period end and the following assumptions: (i) the expected yield based on observable market rate of similar securities, (ii) the security coupon rate that is reset monthly, (iii) the estimated holding period and (iv) a liquidity discount. The liquidity discount assumption is based on the management estimate of lack of marketability discount of similar securities and is determined based on the analysis of financial market trends over time, recent redemptions of securities and other market activities. The Company performed a sensitivity analysis and applying a change of either plus or minus 100 basis points in the liquidity discount does not result in a significantly higher or lower fair value measurement of the auction rate security as of September 30, 2021. Financial Assets and Liabilities Measured on a Recurring Basis The following table sets forth the Company’s financial instruments as of September 30, 2021 and June 30, 2021, which are measured at fair value on a recurring basis by level within the fair value hierarchy. These are classified based on the lowest level of input that is significant to the fair value measurement (in thousands): September 30, 2021 Level 1 Level 2 Level 3 Asset at Assets Money market funds (1) $ 151 $ — $ — $ 151 Certificates of deposit (2) — 862 — 862 Auction rate security — — 1,556 1,556 Total assets measured at fair value $ 151 $ 862 $ 1,556 $ 2,569 June 30, 2021 Level 1 Level 2 Level 3 Asset at Assets Money market funds (1) $ 151 $ — $ — $ 151 Certificates of deposit (2) — 863 — 863 Auction rate security — — 1,556 1,556 Total assets measured at fair value $ 151 $ 863 $ 1,556 $ 2,570 __________________________ (1) $0.2 million and $0.2 million in money market funds are included in restricted cash, non-current in other assets in the condensed consolidated balance sheets as of September 30, 2021 and June 30, 2021, respectively. (2) $0.2 million and $0.2 million in certificates of deposit are included in cash and cash equivalents, $0.3 million and $0.3 million in certificates of deposit are included in prepaid expenses and other assets, and $0.4 million and $0.4 million in certificates of deposit are included in restricted cash, non-current in other assets in the condensed consolidated balance sheets as of September 30, 2021 and June 30, 2021, respectively. On a quarterly basis, the Company also evaluates the current expected credit loss by co nsidering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. For the three months ended September 30, 2021, the credit losses related to the Company’s investments was not significant. There was no movement in the balances of the Company's financial assets measured at fair value on a recurring basis, consisting of investment in an auction rate security, using significant unobservable inputs (Level 3) for the three months ended September 30, 2021 and 2020. There were no transfers between Level 1, Level 2 or Level 3 financial instruments in the three months ended September 30, 2021 and 2020. The following is a summary of the Company’s investment in an auction rate security as of September 30, 2021 and June 30, 2021 (in thousands): Cost Basis Gross Gross Fair Value Auction rate security $ 1,750 $ — $ (194) $ 1,556 No gain or loss was recognized in other comprehensive income for the auction rate security for the three months ended September 30, 2021 and 2020. The Company measures the fair value of outstanding debt for disclosure purposes on a recurring basis. As of September 30, 2021 and June 30, 2021, total debt of $278.8 million and $98.2 million, respectively, was reported at amortized cost. This outstanding debt was classified as Level 2 as it was not actively traded. The amortized cost of the outstanding debt approximates the fair value. Other Financial Assets - Investments into Non-Marketable Equity Securities The Company's non-marketable equity securities are investments in privately held companies without readily determinable fair values in the amount of $1.2 million and $0.1 million as of September 30, 2021 and June 30, 2021, respectively. The Company accounts for these investments at cost less impairment, if any, plus or minus changes from observable price changes in orderly transactions for the identical or similar investments by the same issuer. During the three months ended September 30, 2021 and 2020, the Company did not record any upward or downward adjustments to the carrying values of the non-marketable equity securities related to observable price changes. The Company also did not record any impairment to the carrying values of the non-marketable equity securities during the three months ended September 30, 2021 and 2020.

Ablecom is one of the Company’s major contract manufacturers; Compuware is both a distributor of the Company’s products and a contract manufacturer for the Company. Ablecom’s Chief Executive Officer, Steve Liang, is the brother of Charles Liang, the Company’s President, Chief Executive Officer and Chairman of the Board. Steve Liang and his family members owned approximately 28.8% of Ablecom’s stock and Charles Liang and his spouse, Sara Liu, who is also an officer and director of the Company, collectively owned approximately 10.5% of Ablecom’s capital stock as of September 30, 2021. Bill Liang, a brother of both Charles Liang and Steve Liang, is a member of the Board of Directors of Ablecom. Bill Liang is also the Chief Executive Officer of Compuware, a member of Compuware’s Board of Directors and a holder of a significant equity interest in Compuware. Steve Liang is also a member of Compuware’s Board of Directors and is an equity holder of Compuware. Charles Liang and Sara Liu do not own any capital stock of Compuware and the Company does not own any of Ablecom or Compuware’s capital stock. Dealings with Ablecom The Company has entered into a series of agreements with Ablecom, including multiple product development, production and service agreements, product manufacturing agreements, manufacturing services agreements and lease agreements for warehouse space. Under these agreements, the Company outsources to Ablecom a portion of its design activities and a significant part of its server chassis manufacturing as well as an immaterial portion of other components. Ablecom manufactured approximately 92.5% and 93.6% of the chassis included in the products sold by the Company during the three months ended September 30, 2021 and 2020, respectively. With respect to design activities, Ablecom generally agrees to design certain agreed-upon products according to the Company’s specifications, and further agrees to build the tools needed to manufacture the products. The Company pays Ablecom for the design and engineering services, and further agrees to pay Ablecom for the tooling. The Company retains full ownership of any intellectual property resulting from the design of these products and tooling. With respect to the manufacturing aspects of the relationship, Ablecom purchases most of materials needed to manufacture the chassis from third parties and the Company provides certain components used in the manufacturing process (such as power supplies) to Ablecom through consignment or sales transactions. Ablecom uses these materials and components to manufacture the completed chassis and then sell them back to the Company. For the components purchased from the Company, Ablecom sells the components back to the Company at a price equal to the price at which the Company sold the components to Ablecom. The Company and Ablecom frequently review and negotiate the prices of the chassis the Company purchases from Ablecom. In addition to inventory purchases, the Company also incurs other costs associated with design services, tooling and other miscellaneous costs from Ablecom. The Company’s exposure to financial loss as a result of its involvement with Ablecom is limited to potential losses on its purchase orders in the event of an unforeseen decline in the market price and/or demand of the Company’s products such that the Company incurs a loss on the sale or cannot sell the products. Outstanding purchase orders from the Company to Ablecom were $36.7 million and $40.2 million at September 30, 2021 and June 30, 2021, respectively, effectively representing the exposure to financial loss. The Company does not directly or indirectly guarantee any obligations of Ablecom, or any losses that the equity holders of Ablecom may suffer. Since Ablecom manufactures substantially all the chassis that the Company incorporates into its products, if Ablecom were to suddenly be unable to manufacture chassis for the Company, the Company’s business could suffer if the Company is unable to quickly qualify substitute suppliers who can supply high-quality chassis to the Company in volume and at acceptable prices. Dealings with Compuware The Company has entered into a distribution agreement with Compuware, under which the Company appointed Compuware as a non-exclusive distributor of the Company’s products in Taiwan, China and Australia. Compuware assumes the responsibility to install the Company's products at the site of the end customer, if required, and administers customer support in exchange for a discount from the Company's standard price for its purchases. The Company also has entered into a series of agreements with Compuware, including multiple product development, production and service agreements, product manufacturing agreements, and lease agreements for office space. Under these agreements, the Company outsources to Compuware a portion of its design activities and a significant part of its power supplies manufacturing as well as an immaterial portion of other components. With respect to design activities, Compuware generally agrees to design certain agreed-upon products according to the Company’s specifications, and further agrees to build the tools needed to manufacture the products. The Company pays Compuware for the design and engineering services, and further agrees to pay Compuware for the tooling. The Company retains full ownership of any intellectual property resulting from the design of these products and tooling. With respect to the manufacturing aspects of the relationship, Compuware purchases most of materials needed to manufacture the power supplies from outside markets and uses these materials to manufacture the products and then sell those products to the Company. The Company and Compuware frequently review and negotiate the prices of the power supplies the Company purchases from Compuware. Compuware also manufactures motherboards, backplanes and other components used on printed circuit boards for the Company. The Company sells to Compuware most of the components needed to manufacture the above products. Compuware uses the components to manufacture the products and then sells the products back to the Company at a purchase price equal to the price at which the Company sold the components to Compuware, plus a “manufacturing value added” fee and other miscellaneous charges and costs including overhead and labor. The Company and Compuware frequently review and negotiate the amount of the “manufacturing value added” fee that will be included in the price of the products the Company purchases from Compuware. In addition to the inventory purchases, the Company also incurs costs associated with design services, tooling assets, and miscellaneous costs. The Company’s exposure to financial loss as a result of its involvement with Compuware is limited to potential losses on its purchase orders in the event of an unforeseen decline in the market price and/or demand of the Company’s products such that the Company incurs a loss on the sale or cannot sell the products. Outstanding purchase orders from the Company to Compuware were $87.8 million and $71.0 million at September 30, 2021 and June 30, 2021, respectively, effectively representing the exposure to financial loss. The Company does not directly or indirectly guarantee any obligations of Compuware, or any losses that the equity holders of Compuware may suffer. Dealings with Investment in a Corporate Venture In October 2016, the Company entered into agreements pursuant to which the Company contributed certain technology rights in connection with an investment in a privately-held company (the "Corporate Venture") located in China to expand the Company's presence in China. The Corporate Venture is 30% owned by the Company and 70% owned by another company in China. The transaction was closed in the third fiscal quarter of 2017 and the investment is accounted for using the equity method. As such, the Corporate Venture is also a related party. The Company recorded a deferred gain related to the contribution of certain technology rights. As of September 30, 2021 and June 30, 2021, the Company had unamortized deferred gain balance of $0.5 million and $1.0 million, respectively, in accrued liabilities and none in other long-term liabilities in the Company’s condensed consolidated balance sheets. The Company monitors the investment for events or circumstances indicative of potential impairment and makes appropriate reductions in carrying values if it determines that an impairment charge is required. In June 2020, the third-party parent company that controls the Corporate Venture was placed on a U.S. government export control list, along with several of the third party parent's related entities and a separate listing for one of its subsidiaries. The Corporate Venture is not itself a restricted party. The Company has concluded that the Corporate Venture is in compliance with the new restrictions. The Company does not believe that the equity investment carrying value is impacted as of September 30, 2021. No impairment charge was recorded for the three months ended September 30, 2021 and 2020, respectively. The Company sold products to the Corporate Venture and the Company’s share of intra-entity profits on the products that remained unsold by the Corporate Venture have been eliminated and have reduced the carrying value of the Company’s investment in the Corporate Venture. To the extent that the elimination of intra-entity profits reduces the investment balance below zero, such amounts are recorded within accrued liabilities. Dealings with Monolithic Power Systems, Inc. The Company procures certain semiconductor products from Monolithic Power Systems, Inc. (“MPS”), a fabless manufacturer of high-performance analog and mixed-signal semiconductors, for use in its products. A member on the Board of Directors, also serves as an officer of MPS. The Company had the following balances related to transactions with its related parties as of September 30, 2021 and June 30, 2021 (in thousands): Ablecom Compuware Corporate Venture MPS Total September 30, 2021 June 30, 2021 September 30, 2021 June 30, 2021 September 30, 2021 June 30, 2021 September 30, 2021 June 30, 2021 September 30, 2021 June 30, 2021 Accounts receivable $ 2 $ 2 $ 1,332 $ 198 $ 12,659 $ 8,478 $ — $ — $ 13,993 $ 8,678 Other receivable (1) $ 4,428 $ 5,575 $ 21,690 $ 18,173 $ — $ — $ 165 $ 89 $ 26,283 $ 23,837 Accounts payable $ 40,730 $ 38,152 $ 37,024 $ 31,944 $ — $ — $ — $ — $ 77,754 $ 70,096 Accrued liabilities (2) $ 1,813 $ 3,042 $ 17,790 $ 14,486 $ 500 $ 1,000 $ — $ — $ 20,103 $ 18,528 (1) Other receivables include receivables from vendors included in prepaid and other current assets.

Share-based Payment Arrangement [Abstract]
Stock-based Compensation and Stockholders' Equity	Stock-based Compensation and Stockholders' Equity Equity Incentive Plan On June 5, 2020, the stockholders of the Company approved the 2020 Equity and Incentive Compensation Plan (the "2020 Plan"). The maximum number of shares available under the 2020 Plan is 5,000,000 plus 1,045,000 shares of common stock that remained available for future awards under the 2016 Equity Incentive Plan (the “2016 Plan”), at the time of adoption of the 2020 Plan. No other awards can be granted under the 2016 Plan. 7,246,000 shares of common stock remain reserved for outstanding awards issued under the 2016 Plan at the time of adoption of the 2020 Plan. As of September 30, 2021, the Company had 2,385,365 authorized shares available for future issuance under the 2020 Plan. Common Stock Repurchase On January 29, 2021, a duly authorized subcommittee of the Board of Directors approved a share repurchase program to repurchase up to an aggregate of $200.0 million of the Company's common stock at market prices. The program is effective until the earlier of July 31, 2022 or the date when the maximum amount of common stock is repurchased. The Company had $150.0 million of remaining availability under the share repurchase program as of September 30, 2021. There were no shares repurchased under the share repurchase program during the three months ended September 30, 2021. Determining Fair Value The Company's fair value of RSUs and PRSUs is based on the closing market price of the Company's common stock on the date of grant. The Company estimates the fair value of stock options granted using the Black-Scholes-option-pricing model. This fair value is then amortized ratably over the requisite service periods of the awards, which is generally the vesting period. The key inputs in using the Black-Scholes-option-pricing model were as follows: Expected Term—The Company’s expected term represents the period that the Company’s stock-based awards are expected to be outstanding and was determined based on the Company's historical experience. Expected Volatility—Expected volatility is based on the Company's historical volatility. Expected Dividend—The Black-Scholes valuation model calls for a single expected dividend yield as an input and the Company has no plans to pay dividends. Risk-Free Interest Rate—The risk-free interest rate used in the Black-Scholes valuation method is based on the United States Treasury zero coupon issues in effect at the time of grant for periods corresponding with the expected term of option. The fair value of stock option grants for the three months ended September 30, 2021 and 2020 was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions: Three Months Ended 2021 2020 Risk-free interest rate 0.81 % 0.27% Expected term 6.09 years 5.98 years Dividend yield — % — % Volatility 49.71 % 50.43% Weighted-average fair value $ 17.94 $ 14.16 The following table shows total stock-based compensation expense included in the condensed consolidated statements of operations for the three months ended September 30, 2021 and 2020 (in thousands): Three Months Ended 2021 2020 Cost of sales $ 447 $ 503 Research and development 3,880 3,702 Sales and marketing 517 517 General and administrative 2,171 2,448 Stock-based compensation expense before taxes 7,015 7,170 Income tax impact (1,888) (1,955) Stock-based compensation expense, net $ 5,127 $ 5,215 As of September 30, 2021, $9.4 million of unrecognized compensation expense related to stock options is expected to be recognized over a weighted-average period of 3.85 years, $51.2 million of unrecognized compensation cost related to unvested RSUs is expected to be recognized over a weighted-average period of 2.77 years and less than $0.1 million of unrecognized compensation cost related to unvested PRSUs is expected to be recognized over a period of 0.11 years. Additionally, as described below, $9.6 million of unrecognized compensation cost related to the 2021 CEO Performance Stock Option is expected to be recognized over a period of 5.0 years. Stock Option Activity In March 2021, the Company’s Compensation Committee of the Board of Directors (the “Compensation Committee”) approved the grant of a stock option award for 1,000,000 common stock shares to the Company’s CEO (the “2021 CEO Performance Stock Option”). The 2021 CEO Performance Stock Option has five vesting tranches with a vesting schedule based entirely on the attainment of operational milestones (performance conditions) and market conditions, assuming (1) continued employment either as the CEO or in such capacity as agreed upon between the Company’s CEO and the Board of Directors and (2) service through each vesting date. Each of the five vesting tranches of the 2021 CEO Performance Stock Option will vest upon certification by the Compensation Committee that both (i) the market price milestone for such tranche, which begins at $45.00 per share for the first tranche and increases up to $120.00 per share thereafter (based on a 60 calendar day trailing average, counting only trading days), has been achieved, and (ii) any one of the following five operational milestones focused on total revenue, as reported under U.S. GAAP, have been achieved for the previous four consecutive fiscal quarters. Upon vesting and exercise, including the payment of the exercise price of $45.00 per share, prior to March 2, 2024, the Company’s CEO must hold shares that he acquires until March 2, 2024, other than those shares sold pursuant to a cashless exercise where shares are simultaneously sold to pay for the exercise price and any required tax withholding. The achievement status of the operational and stock price milestones as of September 30, 2021 was as follows: Annualized Revenue Milestone Achievement Status Stock Price Milestone Achievement Status (in billions) $4.0 Probable $45 Not met $4.8 Probable $60 Not met $5.8 Probable $75 Not met $6.8 Probable $95 Not met $8.0 — $120 Not met On the grant date, a Monte Carlo simulation was used to determine for each tranche (i) a fixed expense amount for such tranche and (ii) the future time when the market price milestone for such tranche was expected to be achieved, or its “expected market price milestone achievement time.” Separately, based on a subjective assessment of the Company’s future financial performance, each quarter, the Company will determine whether achievement is probable for each operational milestone that has not previously been achieved or deemed probable of achievement, and, if so, the future time when the Company expects to achieve that operational milestone, or its “expected operational milestone achievement time.” When the Company first determines that an operational milestone has become probable of being achieved, the Company will allocate the entire expense for the related tranche over the number of quarters between the grant date and the then-applicable “expected vesting time.” The “expected vesting time” at any given time is the later of (i) the expected operational milestone achievement time (if the related operational milestone has not yet been achieved) and (ii) the expected market price milestone achievement time (if the related market price milestone has not yet been achieved). The Company will immediately recognize a catch-up expense for all accumulated expenses from the grant date through the quarter in which the operational milestone was first deemed probable of being achieved. Each quarter thereafter, the Company will recognize the prorated portion of the then-remaining expense for the tranche based on the number of quarters between such quarter and the then-applicable expected vesting time, except that upon vesting of a tranche, all remaining expenses for that tranche will be immediately recognized. During the three months ended September 30, 2021, the Company recognized compensation expense related to the 2021 CEO Performance Stock Option of $0.9 million. No compensation expense related to the 2021 CEO Performance Stock Option was recognized during the three months ended September 30, 2020. As of September 30, 2021 and June 30, 2021, the Company had $9.6 million and $10.5 million, respectively, in unrecognized compensation cost related to the 2021 CEO Performance Stock Option. The unrecognized compensation cost as of September 30, 2021 is expected to be recognized over a period of five years. The following table summarizes stock option activity during the three months ended September 30, 2021 under all plans: Options Weighted Weighted Balance as of June 30, 2021 5,175,554 $ 26.17 Granted 114,860 $ 37.88 Exercised (389,942) $ 17.25 Forfeited/Cancelled (41,459) $ 30.47 Balance as of September 30, 2021 4,859,013 $ 27.13 5.52 Options vested and exercisable at September 30, 2021 3,099,511 $ 20.82 3.47 RSU and PRSU Activity In January 2015, the Company began to grant RSUs to employees. The Company grants RSUs to certain employees as part of its regular employee equity compensation review program as well as to selected new hires. RSUs are typically service based share awards that entitle the holder to receive freely tradable shares of the Company's common stock upon vesting. In March 2020, the Compensation Committee granted a PRSU award to one of the Company's senior executives. The award vests in two tranches and includes service and performance conditions. Each tranche has 15,000 RSUs that vest in May 2021 and November 2021 based on service conditions only. Additional units can be earned based on revenue growth percentage in fiscal year 2020 compared to fiscal year 2019, which units would vest in May 2021, and based on revenue growth percentage in fiscal year 2021 compared to fiscal year 2020, which units would vest in November 2021. No additional units were earned for fiscal year 2020 as revenue decreased from fiscal year 2019. An additional 2,939 units were earned for fiscal year 2021 that would vest on November 10, 2021. The following table summarizes RSU and PRSU activity during the three months ended September 30, 2021 under all plans: Time-Based RSUs Weighted PRSUs Weighted Balance as of June 30, 2021 1,854,956 $ 26.79 15,000 $ 34.27 Granted 359,405 $ 37.88 — $ — Released (173,771) $ 22.92 — $ — Forfeited (87,894) $ 27.54 — $ — Balance as of September 30, 2021 1,952,696 $ 29.15 15,000 $ 34.27

Income Taxes

Income Taxes	3 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recorded a provision for income taxes of $3.3 million and $3.7 million for the three months ended September 30, 2021 and 2020, respectively. The effective tax rate was 11.7% and 12.7% for the three months ended September 30, 2021 and 2020, respectively. The effective tax rate for the three months ended September 30, 2021 is lower than that for the three months ended September 30, 2020, primarily due to a decrease in certain non-deductible expenses and a decrease in foreign tax liability. As of September 30, 2021, the Company had gross unrecognized tax benefits of $45.1 million, of which, $28.3 million, if recognized, would affect the Company's effective tax rate. During the three months ended September 30, 2021, there was a $4.3 million increase in gross unrecognized tax benefits. The Company’s policy is to include interest and penalties related to unrecognized tax benefits within the provision for taxes on the condensed consolidated statements of operations. As of September 30, 2021, the Company had accrued $2.7 million of interest and penalties relating to unrecognized tax benefits. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted. The CARES Act provides temporary relief from certain aspects of the 2017 Tax Reform Act that imposed limitations on the utilization of certain losses, interest expense deductions and alternative minimum tax credits and made a technical correction to the 2017 Tax Reform Act related to the depreciable life of qualified improvement property. The CARES Act does not have a material impact on the Company. The Company has determined that its foreign undistributed earnings are indefinitely reinvested except for undistributed earnings related to the Company's operations in the Netherlands. The Company may repatriate certain foreign earnings from the Netherlands that have been previously taxed in the U.S. The tax impact of such repatriation is estimated to be immaterial. The Company believes that it has adequately provided reserves for all uncertain tax positions; however, amounts asserted by tax authorities could be greater or less than the Company’s current position. Accordingly, the Company’s provision on federal, state and foreign tax related matters to be recorded in the future may change as revised estimates are made or as the underlying matters are settled or otherwise resolved.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation and Claims— On February 8, 2018, two putative class action complaints were filed against the Company, the Company's Chief Executive Officer, and the Company's former Chief Financial Officer in the U.S. District Court for the Northern District of California ( Hessefort v. Super Micro Computer, Inc., et al. , No. 18-cv-00838 and United Union of Roofers v. Super Micro Computer, Inc., et al. , No. 18-cv-00850 ). The complaints contain similar allegations, claiming that the defendants violated Section 10(b) of the Securities Exchange Act due to alleged misrepresentations and/or omissions in public statements regarding recognition of revenue. The court subsequently appointed New York Hotel Trades Council & Hotel Association of New York City, Inc. Pension Fund as lead plaintiff. The lead plaintiff then filed an amended complaint naming the Company's Senior Vice President of Investor Relations as an additional defendant. On June 21, 2019, the lead plaintiff filed a further amended complaint naming the Company's former Senior Vice President of International Sales, Corporate Secretary, and Director as an additional defendant. On July 26, 2019, the Company filed a motion to dismiss the complaint. On March 23, 2020, the Court granted the Company’s motion to dismiss the complaint, with leave for lead plaintiff to file an amended complaint within 30 days. On April 22, 2020, lead plaintiff filed a further amended complaint. On June 15, 2020, the Company filed a motion to dismiss the further amended complaint, the hearing for which was calendared for September 23, 2020; however, the Court held a conference on September 15 to discuss how the Court could efficiently address the recent SEC settlement agreement. The parties stipulated to allow plaintiffs to further amend the complaint solely to add allegations relating to the SEC settlement. On October 14, 2020, plaintiffs filed a Fourth Amended Complaint. On October 28, 2020, defendants filed a supplemental motion to dismiss. On March 29, 2021, the Court granted in part and denied in part defendants’ motions to dismiss. Plaintiffs’ claims under Sections 10(b) and 20 of the Exchange Act were dismissed with prejudice as against the Company’s former head of Investor Relations, Perry Hayes. Plaintiffs’ Section 10(b) claim, but not the Section 20 claim, was likewise dismissed as to Wally Liaw, a founder, former director, and former SVP of International Sales. The Court denied the motions to dismiss the Section 10(b) and Section 20 claims against the Company, Charles Liang, and Howard Hideshima, the Company’s former CFO. Discovery has commenced, and the Court has calendared a hearing on class certification for January 22, 2022. The Company intends to defend the lawsuit vigorously. On October 27, 2020, certain current and former directors and officers of the Company were named as defendants in a putative derivative lawsuit filed in the Superior Court of the State of California, County of Santa Clara (the “Court”), captioned Barry v. Liang, et al., 20-CV-372190. The Company was also named as a nominal defendant. The complaint purports to allege claims for breaches of fiduciary duties, waste of corporate assets, and unjust enrichment arising out of allegations that the Company’s officers and directors caused the Company to issue false and misleading statements about recognition of revenue and the effectiveness of its internal controls, failed to adopt and implement effective internal controls, and failed to timely file various reports with the Securities and Exchange Commission. Defendants filed demurrers, which were set for hearing on August 4, 2021, but which were continued to September 15, 2021. Following this continuance, on July 21, 2021, Plaintiffs' counsel filed an amended complaint in lieu of responding to the demurrer. The amended complaint added no new claims; primarily, the amendment added allegations describing the March 29, 2021 motion to dismiss decision in the Hessefort class action. Defendants demurred to the amended complaint on August 24, 2021, and the Court has calendared the hearing for January 26, 2022. The case is otherwise currently stayed. The Company intends to defend the lawsuit vigorously. On May 5, 2021, certain current and former directors and officers of the Company were named as defendants in a putative derivative lawsuit filed in the U.S. District Court for the Northern District of California, captioned Stein v. Liang, et al ., Case No. 3:21-cv-03357-KAW (the “Stein Derivative Action”). The Company was also named as a nominal defendant. The complaint purports to allege claims for breaches of fiduciary duties, waste of corporate assets, unjust enrichment, and contribution for violations of federal securities laws arising out of allegations that the Company’s officers and directors caused the Company to issue false and misleading statements about recognition of revenue and the effectiveness of its internal controls, failed to adopt and implement effective internal controls, and failed to timely file various reports with the Securities and Exchange Commission. The plaintiff seeks unspecified compensatory damages and other equitable relief. Defendants filed motions to dismiss the complaint on August 6, 2021. Rather than oppose defendants’ motions, plaintiff informed defendants that plaintiff was prepared to dismiss his action with prejudice. On September 29, 2021, the parties submitted a stipulation for dismissal with prejudice as to the named plaintiff to the Court for its approval. On October 27, 2021, the Court issued an order for the parties to submit within 30 days a plan of notice of dismissal for the Court’s approval. The Court noted that, if no shareholder seeks to intervene during the notice period, plaintiff may file an administrative motion requesting that the Court dismiss the lawsuit with prejudice SEC Matter— The Company cooperated with the SEC in its investigation of marketing expenses that contained certain irregularities discovered by Company management, which irregularities were disclosed on August 31, 2015, and the Company cooperated with the SEC in its further investigation of the matters underlying the Company’s inability to timely file its Form 10-K for the fiscal year ended June 30, 2017 and concerning the publication of a false and widely discredited news article in October 2018 concerning the Company’s products. On August 25, 2020, to fully resolve all matters under investigation, the Company consented to entry of an Order Instituting Cease-and-Desist Proceedings Pursuant to Section 8A of the Securities Act of 1933 and Section 21C of the Securities Exchange Act of 1934, Making Findings, and Imposing a Cease-and-Desist Order (“Order”), as announced by the SEC. The Company admitted the SEC’s jurisdiction over the Company and the subject matter of the proceedings, but otherwise neither admitted nor denied the SEC’s findings, as described in the Order. The Company agreed to cease and desist from committing or causing any violations and any future violations of Sections 17(a)(2) and (3) of the Securities Act and Sections 13(a), 13(b)(2)(A), and 13(b)(2)(B), of the Exchange Act and Rules 12b-20, 13a-1, 13a-11, and 13a-13 thereunder. The Company agreed and paid a civil money penalty of $17,500,000 during the three months ended September 30, 2020, which was recorded to general and administrative expense in the Company's condensed consolidated statement of operations. In addition, the Company’s Chief Executive Officer concluded a settlement with the SEC on August 25, 2020, as announced by the SEC. The Company’s Chief Executive Officer paid the Company the sum of $2,122,000 as reimbursement of profits from certain stock sales during the relevant period, pursuant to Section 304 of the Sarbanes-Oxley Act of 2002. The settlement amount was paid during the first quarter of fiscal 2021 and the Company recorded the payment as a credit to general and administrative expense. Other legal proceedings and indemnifications From time to time, the Company has been involved in various legal proceedings arising from the normal course of business activities. The resolution of any such matters have not had a material impact on the Company’s consolidated financial condition, results of operations or liquidity as of September 30, 2021 and any prior periods. The Company has entered into indemnification agreements with its current and former directors and executive officers. Under these agreements, the Company has agreed to indemnify such individuals to the fullest extent permitted by law against liabilities that arise by reason of their status as directors or officers and to advance expenses incurred by such individuals in connection with related legal proceedings. It is not possible to determine the maximum potential amount of payments the Company could be required to make under these agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each claim. However, the Company maintains directors and officers liability insurance coverage to reduce its exposure to such obligations. Purchase Commitments — The Company has agreements to purchase inventory and non-inventory items primarily through the next 12 months. As of September 30, 2021, these remaining noncancelable commitments were $508.2 million, including $124.4 million for related parties. Lease Commitments - See Note 7, "Leases," for a discussion of the Company's operating lease and financing lease commitments.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited condensed consolidated financial statements included herein have been prepared by the Company pursuant to the rules and regulations of the United States Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. The unaudited condensed consolidated financial statements included herein reflect all adjustments, including normal recurring adjustments, which are, in the opinion of management, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the periods presented. The consolidated results of operations for the three months ended September 30, 2021 are not necessarily indicative of the results that may be expected for future quarters or for the fiscal year ending June 30, 2022.
Concentration of Supplier and Credit Risk	Concentration of Supplier RiskCertain materials used by the Company in the manufacturing of its products are available from a limited number of suppliers.Concentration of Credit RiskFinancial instruments which potentially subject the Company to concentration of credit risk consist primarily of cash and cash equivalents, restricted cash, investment in an auction rate security and accounts receivable.
Accounting Pronouncements Recently Adopted and Not Yet Adopted	Accounting Pronouncements Recently Adopted In December 2019, the FASB issued amended guidance, Simplifying the Accounting for Income Taxes , to remove certain exceptions to the general principles from ASC 740 - Income Taxes, and to improve consistent application of U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. The guidance is effective for the Company from July 1, 2021. The adoption of the guidance did not have a material impact on its condensed consolidated financial statements and disclosures. Accounting Pronouncements Not Yet Adopted In March 2020, the FASB issued authoritative guidance, Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The new guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference LIBOR or another reference rate expected to be discontinued. The guidance also establishes (1) a general contract modification principle that entities can apply in other areas that may be affected by reference rate reform and (2) certain elective hedge accounting expedients. The amendment is effective for all entities through December 31, 2022. In January 2021, the FASB issued further guidance on this topic, which clarified the scope and application of the original guidance. LIBOR is used to calculate the interest on borrowings under the Company's 2018 Bank of America Credit Facility and E.SUN Credit Facility. The 2018 Bank of America Credit Facility was amended on June 28, 2021 which provided for a new maturity date of June 28, 2026 and fallback terms related to LIBOR replacement mechanics. As the amendment had changes not related to LIBOR replacement, optional expedients under this guidance cannot be elected. The E.SUN Credit Facility will terminate on July 29, 2022 before the phase out of LIBOR. Therefore, the Company does not expect the adoption of the guidance to have an impact on its consolidated financial statements and disclosures.
