Efficiency Normal, Light & Super-Light Loads
Efficiency is average at normal loads and low at light loads. At super-light loads, it exceeds Intel’s recommended 70%.
Average Efficiency
The platform’s average efficiency is not that high, especially at 115V, where the PSU is close to the lowest Cybenetics Platinum limit (89%).
Average PF
The APFC converter needs tuning for higher power factor readings.
Average Efficiency 5VSB
The 5VSB rail is efficient.
Vampire Power
Vampire power is increased, primarily at 230V.

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
