ITEM 5.   OTHER EVENTS

     OnLine Power Supply, Inc. ("OPS") announced today that it has submitted its
1,000-watt, 48-volt power supply, the OPS-1000-48, for certification of safety
by Underwriter's Laboratories (UL), and also by TUV Rhineland, Germany for
certification of safety for use in the European Union.

     The OPS-1000-48, the first in a planned series of highly efficient,
isolated, single output products from OPS, will be tested and evaluated by
INTERtest Systems, Inc., of Colorado Springs, Colorado. INTERtest will manage
the process for: (UL), TUV, and CB certification as well as electromagnetic
capability (EMC) testing. CB certification for the European Union indicates a
product has complied with the testing requirements of all of the European Union
countries, as there are some variances from country to country.

     Once the certification process is complete, the OPS-1000-48 will carry the
UL mark for the U.S. and Canada, the TUV mark for international safety
certification, and the CE mark for EMC (CE is the mark evidencing compliance
with CB certification requirements in the European Union).

     The safety certifications are the final steps leading up to production of
the OPS-1000-48 at Saturn Electronics & Engineering Inc. in Monterrey, Mexico,
OPS' manufacturing partner.

     The OPS-1000-48 was submitted for certification following an exhaustive
in-house testing process in the OPS engineering lab.
