Be Quiet Dark Power Pro 10 850W PSU Review

A few weeks ago we had a look at the Dark Power Pro 10 550W power supply, a product with low maximum output but of stunning quality and performance. Although it was a great product, it definitely was not enough for the system of an advanced enthusiast or hardcore gamer. Be Quiet responded to this by sending the 850W version of the same unit in for review, the output of which makes it capable of powering multi-CPU and multi-GPU systems. Can it perform as well as the smaller version though? We will soon find out.

The Dark Power Pro 10 units are the high-end series of Be Quiet, a reputable German manufacturer. This series consist of six units, with their outputs ranging from 550W up to 1200W; however, only the units up to 850W are 80Plus Platinum certified. This also means that today we also have on our bench table the most powerful 80Plus Platinum certified Be Quiet has to offer at this point of time.
