Sharkoon Rebel P20 1200W ATX v3.1 PSU Review

Efficiency Normal, Light & Super-Light Loads

Efficiency is not that high at normal loads, but it is the other way around at light loads. Lastly, with a super light load, the PSU doesn’t meet the 70% recommendation that the ATX spec mentions.

Average Efficiency

The platform’s average efficiency is right on the spot for the Cybenetics Platinum certification at 115V and a little above the corresponding requirement at 230V.

Average PF

The APFC converter needs tuning for higher PF readings.

Average Efficiency 5VSB

The 5VSB rail is efficient.

Vampire Power

Vampire power is low enough at 115V but higher than 0.1W at 230V.
