Yeah it's a very good PSU for sure. As you've pointed out, its unlikely most people will ever hear this unit at full throttle, because it needs some serious load for that to happen.
Of course, if you was hell bent on making it total silent, you could always swap out the fan with a SilenX or something. Not that I'd advise anyone to fiddle inside a PSU :nono:

Jeeze that is a PCP&C rip off if ever I saw one... the silnecer sprigns to mind when I look at that. Similar internal layout, same exhaust fan and positioning etc. But that is a good thing - more manufacturers like PCP&C mean more stable and quality PSU's. A single rail would have been nice but excellent PSU none the less - whopping efficiency!

I think most manufacturers design around multiple rails to stay withing the ATX specification.
BitTech in their review of the Seasonic X900, state the Corsair is actually a 750w psu thats "under-rated" to 620w to guarantee silence. They suggest Seasonic should take the same approach with the X900 i.e. class it as a truly silent/quiet 700w psu. I guess if true in this respect with regards to silence you could argue the pcpwr is more like a corsair a 620w? ...well maybe a bit noisyer
appologies if sounding like a troll as this was not intended! did a lot of research before purchasing my Seasonic X900 from www.xcase.co.uk for £116.32. This is about the same price as the PCPower Silencer 750 quad.
I can tell you this I am running:
Opteron 175 OC from 2.2 to 2.8GHz
X1900XT Crossfire Master + X1900XTX in crossfire OC to 688/1584 core/mem
2x 10000rpm raptors
2x 500GB WD RE2
2x 320GB WD RE
2x 200GB Seagate
1x 180GB IBM GXP IDE
under load the psu is cool and the fan runs idle speeds!

i was wondering about the output, but I guessed it to be around 400-500. i got the Seasonic to replaced my old PCPower 510 SLI turbo cool. I wasn't having much joy running crossfire. the cards were intermitantly not responding a little to frequently for my liking. this was occurring on a non-overclocked crossfire pc with a hard drive count of 6.
