Physically one of the largest PSUs (power supply units) we've tested, the 180mm long BeQuiet DarkPowerPro 750 is a very sleek-looking device, finished in a glossy black and fitted with a 120mm temperature-controlled fluid dynamic bearing fan which helps reduce overall PC noise.
Six individual 12 volt rails help ensure adequate current is available to all key system components via a selection of modular cables. Only the cables you actually want to use need to be connected to the BeQuiet DarkPowerPro 750, keeping your system case free of un-necessary clutter and helping to improve air flow and overall system cooling.
All the BeQuiet DarkPowerPro 750's cables are colour-coded, so it's easy to plug them in the correct sockets without having to compare connectors.
Unique among our test group is the DarkPowerPro's ability to control not only its own fan, but up to three of PC's case fans.
Usually, when you switch off your PC, all fans turn off immediately, but the BeQuiet DarkPowerPro 750 PSU's Enhanced Cooling After System Off technology keeps them spinning for a few minutes after shutdown, ensuring that all systems components are able to cool down gently.
In our performance tests, the BeQuiet DarkPowerPro 750 proved to be most efficient. It achieved an efficiency of 83%-84% no-matter what we threw at it.
Even our 800W test proved to be no problem, despite being 50W above the BeQuiet DarkPowerPro 750's stated 750W rating.
Our one niggle with the BeQuiet DarkPowerPro 750 PSU is the mains power cable which on our review samples protruded rather far from the rear of the PSU, making it rather wobbly and insecure.
