X-bit Labs compared five 500W to 800W power supplies: BFG ES Series BFGR800WESPSU (800W), Enermax MODU82+ EMD525AWT (525W), SuperTalent Atomic Juice PS-700 (700W), Thermaltake Toughpower QFan 650 A (W0163RU, 650W) and
Xigmatek “No Rules Power” NRP-MC651 (650W). This time the reviewer managed to pick a clear winner:
I guess this test session is the rare occasion when I can definitely name one absolute leader. It is the Enermax MODU82+ power supply. Besides neat assembly and superb electric properties, it proved to be so quiet that it was virtually silent at low and medium loads and quite comfortable at full load. Surely, the MODU82+ won’t be the noisiness component in a system that can load half-a-kilowatt power supply.
