The transient response is decent at 12V but mediocre on the minor rails, especially at 3.3V, where the voltage level dropped below the limit, without any extra capacitance helping it out.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests, but the 12V and 3.3V rails drop low.
Compared to similar spec PSUs, the 12V rail’s performance isn’t that good in these tests.

Hi! I am tempted to buy the Asus Rog Strix 1200w ATX 3.1, but after reading your review I got a bit discouraged, I’m between the asus, the nzxt c1200 and the corsair RM1000x, which do you think is best for something like the RTX 5090? Thank you!
