                          Independent Auditors' Report

The 401(k) Plan Committee
American Power Conversion Corporation:

We  have  audited the accompanying statements of net assets available  for  plan
benefits  of  the  American  Power Conversion  Corporation  401(k)  Plan  as  of
December 31, 2002 and 2001, and the related statements of changes in net  assets
available for plan benefits for the years then ended. These financial statements
are  the  responsibility  of the Plan's management.  Our  responsibility  is  to
express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in  the  United  States of America. Those standards require  that  we  plan  and
perform  the  audit to obtain reasonable assurance about whether  the  financial
statements are free of material misstatement. An audit includes examining, on  a
test  basis,  evidence supporting the amounts and disclosures in  the  financial
statements. An audit also includes assessing the accounting principles used  and
significant  estimates  made by management, as well as  evaluating  the  overall
financial  statement  presentation.  We  believe  that  our  audits  provide   a
reasonable basis for our opinion.

In  our  opinion, the financial statements referred to above present fairly,  in
all  material  respects,  the net assets available  for  plan  benefits  of  the
American  Power Conversion Corporation 401(k) Plan as of December 31,  2002  and
2001,  and  the changes in net assets available for plan benefits for the  years
then  ended, in conformity with accounting principles generally accepted in  the
United States of America.

Our  audits  were  made  for the purpose of forming  an  opinion  on  the  basic
financial statements taken as a whole. The supplemental Schedule of Assets (Held
at End of Year) is presented for the purpose of additional analysis and is not a
required   part   of  the  basic  financial  statements,  but  is  supplementary
information  required  by the Department of Labor's Rules  and  Regulations  for
Reporting  and Disclosure under the Employee Retirement Income Security  Act  of
1974. This supplemental schedule is the responsibility of the Plan's management.
The  supplemental schedule has been subjected to the auditing procedures applied
in  the audit of the basic financial statements as of December 31, 2002, and  in
our  opinion, is fairly stated in all material respects in relation to the basic
financial statements taken as a whole.

                     Notes to Consolidated Financial Statements

                            December 31, 2002 and 2001




(1) Description of Plan

  The  following brief description of the American Power Conversion Corporation
  401(k)  Plan  (the  Plan)  provides  only general  information.  Participants
  should  refer  to the Plan agreement for a more complete description  of  the
  Plan's provisions.

  (a)  General

       The  Plan  is  a  qualified defined contribution plan  covering  American
       Power  Conversion Corporation (the Company) employees who have  completed
       at  least  45 days of service with the Company. The Plan covers all  U.S.
       employees  working for the Company and the Participating Affiliates,  APC
       America,  Inc.,  APC  Sales and Service Corporation, Systems  Enhancement
       Corporation,  Advanced  Power, Inc., ABL Electronics  Corp.  and  Airflow
       Company.   The  Plan  is  subject  to  the  provisions  of  the  Employee
       Retirement Income Security Act of 1974 (ERISA).

  (b)  Contributions

       The  maximum  salary savings (pre-tax) contribution that an employee  may
       elect  to  contribute to the Plan is the lesser of 15%  of  annual  gross
       compensation  or the limit established by the IRS ($11,000 for  2002  and
       $10,500   for   2001).  The  Company  may  match  this   salary   savings
       contribution  at a rate of up to 100% of the first 3%, and  during  1999,
       the  Plan  was  amended  to  match up to  50%  of  the  next  3%  of  the
       participant's   salary   and   wage  compensation,   excluding   bonuses,
       commissions,  incentive  compensation, taxable  fringe  benefits,  moving
       expenses,  auto  and other allowances, and disqualifying dispositions  of
       Company stock. Matching contributions are subject to a maximum amount  of
       6%  per  participant.  The  Company may also make  discretionary  profit-
       sharing  contributions  to the Plan. All employer  matching  and  profit-
       sharing  contributions  are  deposited to the American  Power  Conversion
       Corporation Common Stock Fund.

       There were no discretionary contributions made for the 2002 or 2001  Plan
       year.

  (c)  Vesting

       Participants  are  fully  vested to the extent of  their  salary  savings
       contributions and earnings on those contributions. Furthermore, the  Plan
       was  amended  in 1999, such that participants are immediately  vested  in
       employer  matching contributions and the related earnings.  However,  any
       discretionary  (profit-sharing) contributions vest on a schedule  of  25%
       after  2  years  of  service, and an additional 25% per  year  thereafter
       until 100% vesting is reached after 5 years of service.

  (d)  Loans to Participants

       Participants  may borrow from their vested account balance under  certain
       circumstances as provided in the Plan agreement. The minimum loan  amount
       is  $1,000 and participants may borrow the lesser of 50% of their  vested
       account  balance  or  $50,000.  Interest  on  loans  is  charged  at  the
       prevailing  commercial interest rate for loans of a similar  type  (Prime
       plus  1%)  with a repayment term not to exceed five years. This term  can
       be  extended  if  the loan is used for the purchase of the  participant's
       primary  residence.  A  participant may  not  have  more  than  one  loan
       outstanding at any time.



                                        8





  (e)  Payment of Account Balances

       Upon  termination from the Plan, a participant's vested  accrued  balance
       in   his  or  her  account  shall  be  distributed,  as  elected  by  the
       participant,  in  either  a  single lump-sum payment,  or,  provided  the
       participant's  vested  account exceeds $5,000, in  periodic  installments
       not  to  exceed the participant's lifetime, or the joint lifetime of  the
       participant  and his/her spouse. Distributions may also be made  in  cash
       or  in  kind, or part cash and part in kind over a period not  to  exceed
       the  participant's lifetime, or the joint lifetime of the participant and
       his/her spouse.

  (f)  Hardship Withdrawal

       The  Plan provides for hardship withdrawals, as defined by the Plan, from
       the  participant's  account. Participants who take a hardship  withdrawal
       must  be suspended from contributing to the Plan for a period of 6 months
       following the date of the withdrawal.

  (g)  Forfeitures

       Forfeitures  related  to  discretionary contributions  are  allocated  to
       remaining participants in the succeeding plan year in the ratio that  the
       compensation  of each participant for the plan year bears  to  the  total
       compensation  of all participants entitled to share in the  contributions
       so  long  as  the  forfeiture allocation group meets the requirements  of
       Code  Section  410(b). If the forfeiture allocation group does  not  meet
       the  requirements of Code Section 410(b), then the trustee shall allocate
       non-highly  compensated participants in the forfeiture  allocation  group
       an  amount  in  the  ratio  that  such compensation  of  each  non-highly
       compensated  participant in the group bears to the total compensation  of
       all  non-highly  compensated participants. No forfeiture allocations  are
       made to highly compensated employees.

(2) Summary of Significant Accounting Policies

  (a)  Basis of Presentation

       The  accompanying  financial statements of the Plan  have  been  prepared
       using  the  accrual  basis  of accounting in accordance  with  accounting
       principles generally accepted in the United States of America.

       The  preparation  of financial statements in conformity  with  accounting
       principles  generally accepted in the United States of  America  requires
       estimates and assumptions that affect the reported amounts of assets  and
       liabilities  and disclosure of contingent assets and liabilities  at  the
       date  of  the financial statements and the reported amounts of  additions
       and  deductions  to  net assets available for plan  benefits  during  the
       reporting period. Actual results could differ from those estimates.

  A brief description of each current fund's investment objective follows:

       Merrill  Lynch  Equity Index Trust invests primarily in  a  portfolio  of
       equity  securities  designed  to match the performance  of  the  S&P  500
       Index.

       Merrill   Lynch   Retirement  Preservation   Trust   seeks   to   provide
       preservation  of capital, liquidity, and current income  at  levels  that
       are typically higher than those provided by money market funds.

       Merrill Lynch Equity Income Fund Class A provides shareholders with long-
       term  total  return by investing primarily in a diversified portfolio  of
       dividend-paying  common stocks that yield more than the  S&P  500  Index.
       Total return is the aggregate of income and capital value changes.

       Merrill  Lynch Fundamental Growth Fund Class A seeks long-term growth  of
       capital  by  investing in a diversified portfolio of  equity  securities,
       placing  particular  emphasis on companies  that  have  exhibited  above-
       average growth rates in earnings.

       MFS  Massachusetts Investors Growth seeks to provide long-term growth  of
       capital  and  future  income rather than current  income.  The  fund  may
       invest  up  to  50% of its total assets in foreign securities,  including
       securities of issuers located in developing markets.

       Merrill  Lynch  Basic Value Fund Class A seeks capital appreciation,  and
       secondarily,  income, by investing primarily in equities that  appear  to
       be undervalued.

       Templeton Foreign Fund seeks to achieve long-term capital growth  through
       a  flexible  policy  of investing in the equity and  debt  securities  of
       companies  and governments outside the U.S.  Although the Fund  primarily
       invests  in  common  stocks, it also may invest in preferred  stocks  and
       certain debt securities, rated or unrated.

       Pimco  Total  Return  Fund  Class  A  seeks  to  maximize  total  return,
       consistent   with   preservation  of  capital  and   prudent   investment
       management.   Under normal circumstances, the Fund invests at  least  65%
       of   its   total  assets  in  a  diversified  portfolio  of  fixed-income
       securities of varying maturities.

       MFS  New  Discovery Fund Class A seeks capital appreciation by  investing
       at  least 65% of its total assets in U.S. or foreign companies that  Fund
       management believes offer superior prospects for growth.

       Ariel   Fund  seeks  long-term  capital  appreciation  by  investing   in
       companies with market capitalization primarily under $1.5 billion at  the
       time of investment, with an emphasis on small-cap stocks.

  American  Power  Conversion  Corporation common  stock  is  offered  to  Plan
  participants as an additional investment option. Merrill Lynch purchases  the
  shares  in the open market at the time contributions are received. The timing
  of  all  stock transactions is subject to the availability of American  Power
  Conversion  Corporation common stock on the open market, and prices  are  set
  by the market.

                                        11



(4) Nonparticipant-Directed Investments

  The  employer matching contribution is entirely directed to purchasing shares
  of  common stock of American Power Conversion Corporation. However, once  the
  employer  match  is invested in this fund the participant may reallocate  the
  investment  to  any  of the other funds in the Plan restricted  only  by  the
  closed  employee stock trading periods. Furthermore, employees may  elect  to
  direct  a  portion of their 401(k) contribution towards purchasing shares  of
  common stock of American Power Conversion Corporation.

  Information  about the net assets and the components of the  changes  in  net
  assets  relating  to  shares  of common stock of  American  Power  Conversion
  Corporation is as follows:

(5) Plan Termination

  Although it has not expressed any intent to do so, the Company has the  right
  under  the Plan to discontinue its contributions at any time and to terminate
  the  Plan  subject  to  the  provisions  of  ERISA.  In  the  event  of  Plan
  termination, participants will be fully vested in their accounts.

(6) Tax Status

  The  Internal  Revenue Service has determined and informed the Company  by  a
  letter  dated  October 6, 2000, that the Plan and related trust are  designed
  in  accordance with applicable sections of the Internal Revenue  Code  (IRC).
  Although the Plan has been amended since receiving the determination  letter,
  the  Plan administrator and the Plan's tax counsel believe that the  Plan  is
  designed  and  is currently being operated in compliance with the  applicable
  requirements of the IRC.

(7) Related-Party Transactions

  Certain  Plan  investments  are shares of mutual  funds  managed  by  Merrill
  Lynch.  Merrill  Lynch is the trustee as defined by the Plan and,  therefore,
  these transactions qualify as party-in-interest transactions.

(9) Asset Transfer from Other Plans

  In  December 2002, the Board of Directors of the Company voted to  merge  the
  assets  of  the  American  Power  Conversion Employee  Stock  Ownership  Plan
  ("ESOP")  into the American Power Conversion Corporation 401(k)  Plan  during
  the  2003  Plan  year.  During May 2003, the participants of  the  ESOP  were
  notified  of  the  anticipated merger, which is expected to be  effective  on
  July 1, 2003.
