7-Way 550-600 Watt Power Supply Roundup Review



The results of our electrical efficiency testing are similar to that of their electrical performance, with the exception that the InWin Commander III 600W unit annihilates both Corsair power supplies, with its mean efficiency being about 3.6% higher. Despite that, the Corsair CX600M and GS600 did quite well for 80Plus Bronze certified power supplies, with the GS600 displaying marginally better efficiency as well. The Be Quiet! Dark Power Pro 10 once again dominates the chart, closely followed by Seasonic’s G-Series 550W unit. All three 80Plus Gold certified units have their efficiency mostly unaffected if overloaded, while the efficiency of the 80Plus Bronze certified units plummets.
