Average Noise
The PSU’s average noise output is low. This is one of the quietest 1000W units.
Fan Noise & Speed Maps @ 28-32 °C – 115V
The fan’s passive operation doesn’t last long if you push the minor rails above 85W. Nonetheless, the fan spins at low speeds at up to 695W, so its noise doesn’t exceed 20 dBA. Even at higher loads, noise remains below 30 dBA.
Fan Noise & Speed Maps @ 28-32 °C – 230V
The fan speed profile is identical to the 115V, at 230V. Instead of up to 695W, the fan’s noise remains below 20 dBA at up to 705W.

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
