We have used the local mains voltage of 230V and 50 Hz as well as the American mains voltage of 115V and 60 Hz, where the efficiency is slightly lower but the power factor is slightly higher. On 230 VAC 82% efficiency are already reached at 10% load, where the earlier tested Seasonic X-Series 750W managed to achieve even higher efficiency. Even so Cooler Master keeps its promises as well, because it is only certified with 80Plus Bronze. The result at 115VAC is up to 86.42% efficiency, while at 230VAC 87% are reached.
On 230VAC the efficiency also retains on an acceptable level on 10% overload, while it drops faster below 85% on 115VAC and the Silent Pro completes this measurement with an efficiency of 79.91%. But at 115VAC it can excel with a high power factor, which never falls short of 0.90 and quickly rises up to 0.99. On 230VAC the rise is steeper and the PSU only catches up on higher loads. At its best it delivers a power factor of 0.981.

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.
