The 12V rail’s OCP triggering points are set low and differ enough between cold and hot conditions, so everything is good here. The same goes for the over power protection’s conservatively set triggering points, which have a high enough difference between cold and hot conditions. Moreover, the minor rails have correctly set OCP triggering points, but I would like to see a larger difference between cold and hot conditions. Lastly, all other essential protection features are present and work well, except the fan failure protection. Manufacturers should start implementing this protection because it is crucial!

  1. Your in depth reviews of psu’s are amazing.

    I hope you review the Lian Li Edge 1300 and new phanteks revolt 1200. I want one of those psu’s for my new built.
