Coolermaster takes the silver

The Cooler Master Ultimate Circuit Protection 900W PSU managed an 88% efficiency rating at 80plus.org, a rare level of efficiency for a PSU. TechPowerUp’s testing didn’t quite see the same impressive results, but they were certainly well above average. The cabling was a good news, bad news situtation though; while the interior cables are longer than most, the non-standard power plug was a definate negative. Check out their full reivew for more.
