The transient response is good on all rails but 3.3V.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 3.3V rails drop low.
The 12V rail’s performance in these tests is good enough but not among the best.

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.
