Since this is a relatively low-capacity unit, its 12V OCP triggering points are sky-high to cope with high transient loads. The same goes for the over power protection. The problem is that the 12V OCP cold and hot triggering points are not that far away from each other. Thankfully this is not the case for the respective over power protection triggering points.
The minor rails have high OCP triggering points; to make matters worse, they do not drop at high operating temperatures. Someone must inform all manufacturers that there is no need for such high power levels on the 3.3V rail!

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”.
Anyone knows the OEM of the P10-series?
