The 12V rail’s OCP triggering points are below 130% but are identical under normal and stressful conditions. The OCP triggering points on the minor rails are low but close enough under normal and high temperatures. Having similarly configured OCP triggering points under normal and high temperatures is not wise, showing that the respective engineers didn’t bother tuning the protection features correctly.
Thankfully, the over power protection is correctly set, with a significant enough difference between normal and high temperatures. Lastly, there is no fan failure protection.

hello i want to buy 850w psu, but i’m really confused for choosing which brand. the MPG A850GS is $123, the RM850X is $145, and the Leadex III 850W ATX 3.1 is $100. which one will you recommend between those 3?
I would go for the SF unit.
