Be Quiet Dark Power Pro 10 550W review: high-end power supply

The 550-watt version of Be Quiet's latest high-end series



A while ago we published an extensive round-up of 43 power supplies in the 500-700 watt range. At the time Be Quiet had not yet put the finishing touches on its new Dark Power Pro 10 product line, so we were not able to include it then. In this review we will take a look at Be Quiet's 550-watt model.

The Dark Power Pro 10 is Be Quiet's latest line of high-end power supplies and comes in capacities of 550, 650, 750, 850, 1000 and 1200 watts.The majority of these, including the 550-watt version we are testing here, have an 80 Plus Gold certification. The 850 watt model is even Platinum certified.

The 550-watt model we tested utilises four 12-volt rails, that each supply a maximum of 20, 20, 25 and 25 ampère. The maximum power they can supply together is 45 ampère, or 540 watts. A unique feature that Be Quiet includes is the so-called OC key, a button that lets you combine the 12 volt rails into one rails with the maximum capacity. Overclockers can use the OC key for supplying a heavily overclocked CPU or GPU with enough power, but normal users should just leave it on the standard setting. The 5- and 3.3-volt rails also supply 25 ampère.The peak capacity of the power supply is 610 watts, which it is able to achieve in a constant manner during our test.

The 550-watt Dark Power Pro 10 is a modular power supply, and comes with very solid connectors. You get 7 molex and 9 SATA connectors in the box. For graphics cards you get four 6/8-pin PEG connectors and a 6-pin connector, so five in total. That's a lot for a 550W power supply. All of the modular cables are individually sleeved.

An interesting feature are the four integrated case fan connectors. A temperature sensor on the PCB controls the fans.

The 550-watt Dark Power Pro 10 has a 135 mm fan from its own SilentWings series. It has ribbed blades, and is very silent. The fan grille is made with rounded wires, giving it a nice look and adding to the silent design. To finish things off there is a rubber edge on the side that faces the chassis once it's attached, in order to prevent resonance.

This is not a cheap power supply, with an average price of £110. Of course there are even more expensive power supplies out there, but this Be Quiet power supply is more expensive than average. Interestingly, the Gold Award winner from our large round-up, Seasonic X-Series 560 watt, has the same price. It will therefore be interesting to compare these two power supplies.
