Seasonic Focus GX-750 V4 ATX v3.1 PSU Review

Efficiency Normal, Light & Super-Light Loads

Efficiency is satisfactory at normal loads but not that high at light loads. Lastly, the PSU passes 70% efficiency with a 2% load, which the ATX v3.1 spec recommends.

Average Efficiency

The average efficiency meets the Cybenetics Gold requirements at 115V and 230V input.

Average PF

The APFC converter needs tuning for higher power factor readings.

Average Efficiency 5VSB

It would be nice if the 5VSB rail’s average efficiency exceeded 80% at 230V.

Vampire Power

Vampire power should be lower at 230V.
