Ok I'm going to upgrade my pc this year, starting off first with upgrading my cpu to a A64 X2 3800+ (It fits my mobo), and my gpu to a dx10 card later this year. Question is, I have a 550W power supply is it enough?
for my cpu though i need that extra juice to power the several hd drives, extra fans, optical drives, led lights (lol) and not to mention oc'ing the stuff, i'm sure 40 amps is good if you don't have a billion other things to power. :)
note, ive seen the 8800 gtx's powered by the corsair 620 watter, that's quite awesome, though it has a hefty 50 amps on its 12 volt rail ;)jfelisario
Yep, the 40amp PSU I was talking about was it's little bro, the HX520w. A Corsair Rep personally tested the PSU with dual 8800GTXs and said he hasn't had a problem.
yeah, that's power right there with 50 amps. one question to the ppl here, what do you guys prefer, multi-railed psu's or a single-rail psu's?jfelisario
Well, from my research, single rails usually are extremely stable ripple-wise, though that might just be the PCP&C build quality. Also depending on the exact design of a multi rail psu, some power might be "trapped" on a certain rail and unuseable for other needs.
Multi rails seem to be the cheaper, easier way to get high wattage PSUs, they also seem to be slightly more effiicient.
The problem will be not your PSU, but the rest of your future hardware, if you are planning on buying 8800 GTS or 8800 GTX. 3800 X2 is not enough for these cards. You should worry about upgrading to C2D or getting a 4600+ X2 instead. So you won't get a maximum performance of your GFX unless you get a faster CPU.

yeah i really admire pc power and cooling's build quality, and perhaps undoubtedly the produce the best psu's out there, yeah but don't multi-rails usually produce more cleaner output? at least that's what i heard was one of the pluses for it versus single-railers...

Bottlenecking is completely dependant on the resolution you are playing at...
