The 12V rail’s OCP triggering point is set sky-high, and the same goes for over power protection. Moreover, the differences in the respective triggering points between hot and cold conditions are low. On the other hand, the minor rails are conservatively set, and their triggering points drop notably lower at high temperatures.
The PWR_OK signal is lower than 16ms, which was the ATX v3.0 spec’s lowest limit, but it meets the corresponding low limit of the ATX v3.1 spec, which is 11ms.
