+12V shows excellent regulation, while on the other voltages higher decreases can be noticed. However, all measurements are still in the range of specification. +5V drops to -4% at nearly 21A load, which is just within the specification. This is the weakest regulation in the test, as the +3.3V rail reaches 3.25V at similar load levels, but starts relatively high with 2.72 % (~2A). The 12V rail is really well balanced, because it never falls under -0.5% even at high load (up to 76A during the test). Even +5VSB stays on target at high loads and reaches 4.85V at minimum.

No worries... Even when I say I don't need it, I still don't mind reading about it :)cactusdog - Tuesday, September 7, 2010 - link
My 5870 is silent when idling, most of them are these days so 2X silent is still silent.Fan noise is annoying to me(and others) i spend carefully to avoid noise and i have a silent highend gaming rig. If the manufacturer claims the PSU to be silent it needs to silent.
