The 12V rail’s OCP triggering points are normal for a 750W unit, but similar between low and high temperatures. This is not ideal because the higher the operating temperatures, the higher the stress on the PSU. On the minor rails, the OCP triggering points are set high, especially at 3.3V. Again, the differences in the OCP triggering points between normal and high operating temperatures are minimal.
The OPP triggering points are high, with a small difference between cold and hot temperatures. The rest of the essential protection features are present, but the fan failure is absent; typically, it should exist in a high-end power supply. I want to push all OEMs to include fan failure protection in their designs, even the lower-end ones.
