The transient response is mediocre at 12V and 5V and good enough on the rest rails.
Transient Response ATX v3.0 Tests
The PSU passes all ATX v3.0 transient response tests.
While the 12V rail performs decently in these tests.

I think fsp 1000w ti is still cheaper in my country and performs much better than this psu. I expected more from seasonic tbh.
Disappointing results from Seasonic here particularly from a new line up they advertised them for so long per https://seasonic.com/news/sea-sonic-to-launch-new-vertex/ here.
Thanks for the review ! Appreciate the 115V/230V detail in the Noise output section
I have to admit, I am quite disappointed with this PSU.
I got the PX-1200 model and the Corsair SF1000 (in case I could not manage to fit the Seasonic one in my lian A3-matx), and so far the corsair has been superior despite the lower capacity and form factor. In fact, the corsair is much quieter under low/medium loads, and under high loads, I can only hear my GPU anyway.
Protection features are also quite disappointing with this Vertex series, and efficiency is just marginally higher than the gold certified version
To sum it up, the Corsair SF1000 has been, at least for me:
– quieter
– cheaper
– MUCH less bulky
– ATX 3.1 compliant
