7-Way 550-600 Watt Power Supply Roundup Review

Acoustics

Once again, the Be Quiet! Dark Power Pro 10 550W unit lands at the top of our charts; however, this time it is InWin and the Commander III breathing down their neck, with the Corsair GS600 following closely behind. Seasonic and the G-Series 550W unit comes fourth, with the ADDA ball bearing fan being a bit more whiny than what the company would have liked. Once overloaded, the noise levels of all power supplies will nearly double, or worse.
