Xigmatek NRPPC602 600W review

The Xigmatek 600W PSU is well suited to eco-enthusiasts, with an 85 per cent efficiency rating claimed by the manufacturer, and recycled packaging to boot. In general, home users and casual gamers will benefit by using this PSU. It can certainly deliver power to a wide range of system components, including lower-end PCI Express graphics cards. Under our testing, the Xigmatek 600W achieved 100 per cent of the manufacturer's claimed performance based on real-world scenarios involving the most commonly used 12 volt rails. In terms of total efficiency, the Xigmatek 600W came in at a very respectable third place, behind other entry-level power supplies such as the OCZ StealthXStream 2 600W and the Antec TruePower 550W. It also performed moderately well in terms of standby efficiency; coming in around the middle of the field compared to its rivals.Even under load the PSU produced less decibel noise than all similar power supplies in its class, including the Fractal Design Tesla 650W and the Spire Blackmoon 650W, making it the quietest under test. The large 140mm fan did a good job venting heat, helping to keep the inside of the PC cooler than the outside exhaust, and the cables didn't significantly heat up during high electrical loads.
