This site will take all of your build info and give you a rough estimate of the power needed to run. More than likely the 550w should be enough. My current computer required
462w to run and I went with a Corsair 850w that way I would have ample power and be prepared for a possible upgrade in graphics card or going SLI or 3x SLI in the future.
I highly recommend Corsair, OCZ, and Cooler Master as these three have been very good makers of PSU's for me

Pretty good for a PSU calculator. I've tried many, and most give ridiculous +100% headroom just to be certain. This one demangs 355 W and recommends 405 W. I'm using Corsair HX520W, so with 355 watt load (not that unrealistic constant load if I use Folding@Home or BOINC that keep the overclocked Quad at 100% util, and have 6 HDD spinning) the PSU is running at 68% of it's maximum rated load. (70% (or at least 50-80%) is usually considered to be the sweet spot for best efficiency, and not too stressing for even constant load and years of expected use.)
Yeah, and I also recommend Corsairs: 5 years of warranty, intelligent fan controller that keeps the fan speed low unless you really push it to the edge or if ambient air rises much (or the combination of both). Corsair PSUs are manufactured by Seasonic. And not only are they manufactured there, their build is pretty 'Seasoniccy", the only mentionable difference being that Corsairs have different fan ramp-up to temperature/load relation curve.

Easily - by not using a high-end dual GPU. Two high-end GPUs can easily bump the power usage by 200 W. Of course 500 watts can be enough even for such computers (if noise is no concern and if it's not done 24/7). Theoretically, like the PSU calculator suggests, a tad above 300 watts is barely enough. It's just that I wanted to do 30% overclock and bump the CPU TDP alone to 130 watts and wanted to use it 24/7 for scientific computing while in overclocked state and remaining a quiet HTPC at the same time. No 300-watter would have remained quiet under such load and not necessarily even reliable if pushed that hard for at least 5 years (which is what I would hope the PSU would survive... after all, it's death can cause every other computer component to die along with it).
But yeah, theoretically 300 watts might be barely enough for me. 500 watt might be barely enough for someone with dual high-end GPU. It would probably be ok as long as you don't push it constantly to the limit.

More likely a bad PSU than overloading it to death. Unless of course you did 6 hour gaming sessions in a non-airconditioned room during summer, or ran BOINC or Folding@Home with GPU clients.

sounds about right.. it blew up not long after i made the server first death knight when WOTLK came out for woe... i played 20 hours a day for a week.. then again thats also prolly why i hate ow now

I bought the fan for the thingie. . .thing is I cant place it... it doesnt "stick" because it doesnt come with those plastic like. . .bolts? iono those plastic things that fit it into place. . .it just has sticky thing in the bottom. . .I was thinking of using thermal compound. . .but does that work as glue also?

The sticky thing at the bottom is called thermal tape. You hold it firmly against the chip for about 5 minutes and it should hold pretty securely.

tried it, . .
it went ok on the first try but after the third time I turned it on it fell off. . .
if you look at the chip from the side it looks like this
_______|----|__________
so basically if i were to put that hting on top it would go something lik thi

in which case not all would be touching and not all would be sticking. . .
offcourse thats an exageration of the distance. . .its minimal but its there

it was rosewell i think

It may have been a 550W peak power PSU tested at room temp whereas you should always make sure your PSU is rated at continuous power and at 40°C (or higher).

you may need to just get some screws and screw it in.
