Wow, this is the first post in this thread?


Some reference material others may find useful:


Single Rail Power Supply ATX12VO Design Guide - Intel (pdf spec)
Revision 002, May 2020


ATX12V and ATX12VO PSU Design Guide Addendum - Intel (pdf spec)
Revision 002, May 2021

ATX Multi Rail Desktop Power Supply Design Guide - Intel (pdf spec)
Revision 003, June 2020

ATX Specification - Intel (pdf spec)
Version 2.2 (ca. ~2003 or 2004, don't remember which)

Also possibly of interest, though based on an earlier spec:
LTT - ATX 2.52 (June 2018 rev 002) - Simplified

(it's just a page that makes it a bit easier for laypeople to follow some of things discussed in the specs)


For those interested in making their own cables, a great reference page regarding crimp housings, pins, and the tools used to put them together:

Matt Millman's Common Wire-To-Board, Wire-To-Wire Connectors, And Crimp Tools page
