OCP is set below 130% at 12V and is lower in hot conditions than in cold ones, so it is more effective. Unfortunately, this is not the case on the minor rails, where the OCP triggering points are sky-high, and the differences between cold and hot conditions are small. To effectively protect the PSU, OCP triggering points should be notably lower under harsh (e.g., hot) conditions.

The overpower protection is a bit higher than what I want to see (130-135%), but we didn’t encounter any problems, and it drops closer to 130% at high temperatures.

  1. I found this psu in local online marketplace and it’s about $105,63 (current currency). I was a bit skeptical first because it’s have newest feature in a cheap price. But glad i found this positive review, can’t wait for my next pc build

  2. Aris did you have or receive some ASUS Prime PSU that based on CWT GPX is that good enough as ATX 3.0 psu ?
