Be Quiet! Dark Power Pro 10 650W PSU Review

Testing results (Regulation & Ripple)



Considering the power output and league of the Dark Power Pro 10 650W power supply, the electrical performance is very good. The power supply holds a voltage regulation of 1.5% on the 12V line between 20% and 100% load, an excellent result which only very high performance units currently achieve. The voltage regulation on the 3.3V and 5V lines goes up to 2.4% for the same power range; worse than the 12V line but still well below the psychological “high performance limit” of 3% which most enthusiasts are looking for. Ripple filtering is very good as well, with the worst figure which we recorded being 44mV under maximum load, a mere third of the 120mV design limit.
