The 12V rail’s OCP triggering point is set high; the same goes for over power protection. The differences in the respective triggering points between hot and cold conditions are at normal levels.
The minor rails are conservatively set, and their triggering points drop notably enough 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.

The transformer’s visual impact is remarkable, but it is the optical effect compared to the size of the power supply. Seeing 1200w from such a small 850w power supply always makes a certain sense.
