The Sharkoon Rebel P20 SFX 1000 is a powerful small factor PSU, ideal for strong systems built into small chassis, where a normal ATX PSU won’t fit.
The Sharkoon Rebel P20 SFX 1000 is included in my best ATX v3.x & PCIe 5.x PSU picks article.
Sharkoon released two new power supply lines: one with normal-size ATX members and one with small-form-factor SFX models. I have already evaluated the ATX line, and in today’s review, I will evaluate the strongest member of the SFX line, which has a max power of 1000W.

Andyson builds the Rebel P20 units, and Sirfa provides the platform for the Rebel P20 SFX units. Like the ATX models, the SFX ones feature a fully modular cable design, and they are all rated by Cybenetics, achieving Platinum efficiency, Standard++ (1000W and 850W), and A- (750W) noise ratings. The prices are increased because the smaller the form factor, the higher the cost, with the P20 SFX 1000 going for 200 euros in the EU market! None of the Sharkoon units are available in the US market, and I don’t know if this will change in the future.
