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. 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 identical between cold and hot conditions. They are conservative, but the hot triggering point should be notably lower than the cold one. 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.

Thank you for the detailed review and your time spent for testing the units.
I just bought this unit on Amazon during BlackFriday deal because of good result in your test.
Aris did PCCooler YS1200 basically same PCB parts & design of Seasonic GX/PX-1200 ?
U mean the “Same Platform” thing?
Don’t remember sorry. please check Cybenetics if there is parts description for both units there.
Thank you for all these PSUs reviews !
you are welcome!
