We?ve been huge fans of be quiet's Dark Power Pro power supply series since we were first introduced to it a few years ago. It is no wonder that be quiet! is Germany's number 1 power supply manufacturer. The Dark Power Pro 11 takes the Dark Power Pro series to the next level by adding new power conversion topology that delivers 80PLUS Platinum performance, and an unparalleled array of enhancements that augment this unit's compatibility, convenience of use, reliability, and safety. Be quiet says that this unit is the most technologically-advanced power supply they?ve ever built! The unit also features a semi-modular design so you only use the cables you need, a 135 mm SilentWings 3 fan so you know it is going to be quiet, and an overclocking key which allows switchover between quadruple independent 12V-rail mode and high-performance single-rail operation. The unit comes in wattages 550W ? 1200W and today we are taking a look at the 850W unit, let's see what it can do!
