Sharkoon Rebel P20 750W ATX v3.1 PSU Review

Efficiency Normal, Light & Super-Light Loads

Efficiency is low at normal loads and moderate at light loads. It exceeds 70% with a 2% load, meeting Intel’s corresponding recommendation.

Average Efficiency

The platform’s average efficiency is high enough to meet the Cybenetics Gold requirements.

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.

  1. Ripple suppression is IMHO even remarkable, not only good. I compare to the SilverStone DA750R Gold review on Tomshardware, which is a very similar PSU, probably build on the identical Andyson platform (P32).

    Just compare the part analysis of the Silverstone and the Sharkoon, the inner build is very similar with some light benefits for the P20 (like the better fan):

    Heatsinks and layout are identical. Ignore what the review says (“Internally, the DA750R utilizes a platform from HKC and incorporates Ltec, Teapo and Polycap capacitors”) – this is not true if you check the pictures and they admit the error in the comments.

    Coming back to ripple supression, the Tomshardware-Review of the DA750R by quote: “Ripple suppression is outstanding for a unit of this class, with maximum ripple levels of 28 mV on the 12V rail, 18 mV on the 5V rail, and 18 mV on the 3.3V rail, well within the industry standard limits for this tier.” If this is truly outstanding, then the PA20 750w should be even better, as it has even lower mVs. Whats better than outstanding? Certainly not the word “good”.
