The transient response is mediocre at 12V and 3.3V.
Transient Response ATX v3.1 Tests
The PSU passes all ATX v3.1 transient response tests.
The 12V rail’s performance is good enough at high loads. The difference from the top-performing Corsair SFX unit is notable, though.

I would like to know the noise output of the electric circuit in the PSU. My SF1000 outputs a 14953hz noise, it gives me headache. I would like to get something that don’t have this noise.
On 220V
this is not possible because each PSU once connected to a specific system affects it, so frequency analysis on a single PSU alone won’t mean anything regarding coil whine.
