Noise Level

The HX620 appears to have some very impressive specifications including ~85% efficiency, noise levels of around 35dbA under 100% load and triple +12v rails rated at 18 amps each. Corsair also claims that each of the +12v rails are able to share power, thus meaning that if any one of the 3 rails becomes overloaded, one of the other rails will be able to assist.

"For a ~600w unit the sum of £96 (over at may seem a little higher than most other competing products, however as the saying goes - "You get what you pay for", and this is certainly true for the HX620."
