Sharkoon Rebel P20 SFX 1000W ATX v3.1 PSU Review

Epilogue

The Rebel P20 SFX 1000 is a high-power, small-factor PSU that faces strong competition, mostly from the Corsair SF1000 unit. Currently, this Sharkoon unit is not available in the US market, and in the EU, it costs 200 euros, which is a pretty stiff price. Currently, Corsair’s flagship SF1000 unit goes for about 25 euros more in the EU market, not leaving many chances for the P20 SFX 1000 to have a successful sales career. Sharkoon should drastically change its pricing scheme in this SFX model if it wants to boost its sales. Currently, the P20 SFX 1000 is too expensive for what it has to offer. Moreover, at this price point, I would like to see a higher quality fan, for instance, a Hong Hua one, instead of the mediocre quality Globe Fan model used. Nonetheless, the rest of the parts are of high quality, and the same goes for the soldering quality, which is good.

Performance-wise, efficiency needs boosting, especially at light loads; load regulation needs to get tighter, and the same goes for the unit’s transient response. A larger NTC thermistor would help bring the inrush currents to lower levels, and more filtering caps on the secondary side would improve ripple suppression at 12V. Vampire power also needs to get lower, mostly at 230V. On the other hand, ripple suppression is good on the minor rails, the APFC converter achieves high performance, the 5VSB rail is efficient, and the PSU’s noise output remains below 25 dBA at up to 700W loads. Don’t expect a high-power, small-form-factor PSU to be dead quiet. If silence is a priority for you, then an ATX PSU is preferable, given that your chassis can accommodate it.

The Rebel P20 SFX 1000 needs a price update to remain in the game. The ideal price would be notably below the 200 euros mark. I do not know if Sharkoon can work with Sirfa to make this happen.
