I see lots of PSUs on the Egg but reputable brands are starting around $80 so I may have to compromise. I see PSUs with multiple 12v rails and some with one large 12V rail. What works best, multiple small or one large? Would you recommend a minimum amperage total (say at least 50amps whether in one large rail or spread out into multiple smaller rails)?
I see a person in my area is advertising a Silencer 610EPS12V w/ 49amps on one rail, and 670 peak watts for under $50. Could that possibly be adequate for OCing this 4 1/2 year old Q9450 (or even my AMDs 555BE & 1100T), or do I definitely have to move up to a 750w?
The Corsair CMPSU-400CX only has 30Amps on the 12v rail yet seems to have no problem OCing my 555BE with 4 unlocked cores to 3.6Ghz on a Gigabyte GA-MA785GMT-UD2H , is the Intel such a power hog that it needs so much more raw power?
Thanks for the help and letting me pick your brain a bit
