be quiet! Dark Power Pro 10 850 W Power Supply Review

Conclusions

It is very clear that be quiet! is trying, with the Dark Power Pro 10 series, to create the most flawless and complete PC power supply series available on the market today. The cable configuration of the 850 W is the most complete possible, allowing you to install three high-end video cards out of the box. The single/multiple rail switch puts an end to the endless discussion of which configuration is better: you simply choose which one you think is better. We really loved that this power supply comes with four cables for fans with two power connectors each; this way you can make all the fans available on your case to be temperature-controlled by the power supply.

Performance-wise, the Dark Power Pro 10 850 W presented high efficiency between 88.1% and 91.4%, a bit below the numbers promised by the 80 Plus Platinum certification, but the AC voltage at our lab was at 105 V instead of 115 V, which could have caused this. Noise and ripple levels were very low, and all positive voltages were within 3% of their nominal values.

The only problem we had with this unit was that it burned when we overloaded it to 985 W. This may mean that we got a defective sample, so we asked a second sample from the manufacturer, which should arrive shortly. So, do not hold this result against the manufacturer before we do test the second sample.

Technically, the Dark Power Pro 10 850 W is a good power supply, targeted to users who demand only “the best.” Its price, although high, is not bad for an 850 W unit with 80 Plus Platinum configuration and the number of extra features it brings.
