This document aligns to ATX Specification Version 3.0
This document provides design suggestions for various power supply form factors. The power supplies are primarily intended for use with desktop system designs. It should not be inferred that all power supplies must conform exactly to the content of this document, though there are key parameters that define mechanical fit across a common set of platforms. Since power supply needs vary depending on system configuration, the design specifics described are not intended to support all possible systems. The REQUIRED sections are intended to be followed for all systems. The RECOMMENDED sections could be modified based on system design. Lastly, a few section are labeled as OPTIONAL, which would not be intended for all design but is helpful to some designs.
