The 12V rail’s OCP triggering points are below 130%, but under hot temperatures, the respective point is higher than the one at lower temperatures. It should be the other way around and with a significant difference. In other words, the hot OCP triggering point must be lower to protect the PSU effectively. The same is the situation for OCP on the minor rails, which are also pretty high, especially on the 3.3V rail. Moreover, the OPP triggering points might be well below 130% but are similar between cold and hot conditions. They are conservative, though. Lastly, the PSU has fan failure protection, and this is a big plus since the fan’s operation is crucial for the PSU’s operation.

Hey Aris, thank you for the review. After my long research and your articles, I finally bought this product (it finally arrived in my country). Is it a problem if the 3.3V channel drops below 3.2? If it is a problem, what causes it?
