Interesting... I Have a Q-Tec Dual Fan 550W, they are over rated but pretty
cheap. I think they admitted that the rating is for the peak current, not
the continuous current. Anyway, it's plenty enough for my system.
I haven't noticed any noise from it or caused by it though (apart from the
fans, obviosuly :-) which I have replaced)...
In fact my SoundStorm has been pretty good... there is some background noise
but only at amp levels that would do damage to my ears and speakers should I
actually attempt to produce any sound from it. It's not linked to mouse
movement, scrolling or anything else... it's just the usual background
noise.
Digitised input produces quite a bit of background noise (from an analogue
source), as does mic boost. None of my analogue inputs are loaded which
might not help. (For example, unloaded inputs on my Audio amp (Cambridge
Audio A500) pick up cross-talk from active inputs at maybe -40dB or so, but
when loaded (connected) they do not (well if they do it's probably less
than -80dB - it's hidden in the 50Hz hum))
