This is a low-capacity PSU, so it is expected to have high OCP triggering points, especially at 12V. That said, there is no need for a high amperage at 3.3V, and what worries me most is that the hot and cold OCP triggering points are identical on the minor rails. Usually, the hot OCP triggering point should be notably lower to protect the PSU effectively.
The over power protection is appropriately set, with a large enough gap between cold and hold conditions. Lastly, this platform doesn’t seem to have short circuit protection between -12V and Earth, and although this rail is not used anymore by the majority of mainboards, it can still kill the PSU, so CWT should fix this problem ASAP.
