Taipei, Taiwan, July 28, 2008 – In order to cater to users who require a stable and energy conserving power supply, ASUS, world-leading producer of top-notch power apparatus, has unveiled the new ASUS U-75HA power supply. The U-75HA delivers an outstandingly durable lifespan of 200000 hours – double that of normal power supplies; and is also equipped with four +12V rails and four PCI-E 6+2 pin connectors to provide support for high end graphic cards. The U-75HA is part of ASUS’ U-Series of power supplies – incorporating Active PFC for improved voltage stability and environmentally friendly power delivery. What’s more, all of ASUS’ U-Series power supplies are 80 PLUS certified in accordance to the EPA’s Energy Star 4.0 standard for computers.
"Equipped with accurate power ratings to deliver their full rated power, the ASUS U-75HA is Intel ATX 12V Version 2.3 compliant, and incorporates four real 12V rails (12V1,12V2,12V3,12V4) to provide stable support for high-end graphic cards."
That is enough to put me off from this PSU. I don't plan on ever getting another PSU with more than one 12V rail. If one rail is dedicated to the CPU, and it only uses 1/2 of it, that rail is still completely used up, where as if you have one rail for everything, it is only used up when the PSU is at 100% load.
