The PSU was tested without being connected to a system to adjust its settings through XPG’s application. In other words, it was tested in its default mode, whereas you can see in the table above, OCP is not present at 12V2 and 12V3 rails. The other 12V rails have high OCP triggering points, while OCP is correctly set on the minor rails. Lastly, OCP is set sky-high at 5VSB. This is among the strongest 5VSB circuits I’ve ever encountered.

Over power protection is set below 130%, and the fact that OPP is activated lower under hot conditions is ideal. Lastly, this is among the few PSUs with fan failure protection. If the fan stops by force, the PSU shuts down.
