On the face of it the Corsair HX 650W is particularly suited to standard desktop systems and casual gaming machines. It provides power to a range of system components that include PCI-E and SATA devices. It comes with a robust single 12 volt rail is 80Plus Bronze certified, Nvidia SLI compliant, and is semi-modular.Under our tests, the Corsair HX 650W achieved 100 per cent of the manufacturer's claimed performance based on real-world scenarios involving the most commonly used 12 volt rails. Looking at total efficiency, the Corsair HX 650W came in around the mid-range mark for its class, lagging behind other power supplies such as the Antec TruePower 550W but still ahead of others like the Spire Blackmoon 650W. It did gain substantial ground in terms of standby efficiency; achieving second place from a field of seven similar power supplies. This PSU produced a fraction more decibel noise when compared to most other PSUs in its class like the OCZ StealthXStream 2 600W and the Xigmatek NRPPC602 600W, although the overall noise difference was minor.
