Full review Kitguru Review "Technically, the Dark Power Pro 11 850W delivers the goods. Ripple suppression passed all the tests, and load regulation could be classed as very close to class leading. Efficiency rated at just over 94 percent at close to 50 percent load, which is magnificent... The be quiet! Dark Power Pro 11 850W is a fantastic power supply well suited for a new high end system build." Full review Guru3d Review "This is the flagship product series from Be Quiet! and they have made sure all the boxes are ticked and all variables are done right. The PSU excels in stability, low noise level and efficiency. It is an impressive power supply from A to Z and we can't really find anything that concerns us." Full review /Power Supplies/be quiet!
