The presence of capacity mostly makes itself noticeable in the ripple results. +3.3V starts with a vanishingly low peak-peak value of just 6mV at 10% load, and later it increases to 14mV. +5 V begins with a higher result, but finishes with 23mV at overload, which is well within specification (50mV). On the +12V rail more capacitors are available for voltage straightening, but the currents are significantly higher. Here we have shown the worst case with a larger spike at 110% load at one of the measuring points. But this is still within specification and very decent, as it does not even reach 50% of the allowed level.

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.
