1. Scope
This document outlines a reference ATX power supply that complies with the ATX Specification, Version 2.02 for motherboards and chassis. It is intended to provide additional power supply design information not detailed in the ATX 2.02 specification, including information about the physical form factor of the power supply, cooling requirements, connector configuration, and pertinent electrical and signal timing specifications.
This document is provided as a convenience only and is not intended to replace or supplement the user’s independent design and validation activity. It should not be inferred that all ATX power supplies must conform exactly to the content of this document. Neither are the design specifics described herein intended to support all possible system configurations, as system power supply needs will vary widely depending on application (desktop / workstation / server), intended ambient environment (temperature, line voltage), motherboard power requirements, etc.
With a few modifications, a standard PS/2† power supply can support an ATX
