I was a lucky one, got one new fromnewegg last night for $219 and free 2 day shipping! I was gonna get two, since they were so cheap, but had to wait for today to get some more moolah, and they're already sold out.

Will a 750W psu be enough to run that 480 by itself and an overclocked 2500k (haven't tried overclocking yet, not enough cooling)?

I ran a 480 sli briefly with an hx750. As long as it's a solid unit, you should have no issues whatsoever.

A good quality 750W PSU is just enough but be careful not to OC.

Wrong.

A 750W is plenty. And you can overclock. My 2700K + 480 both overclocked alot pull less than 600W. I know this because I tested it. A 750 would go SLI fine with only a small overclock (don't touch voltage). 850 for high overclocks.

yeah, this is way wrong. I ran two reference 480's for 10 minutes in furmark at 750 core with a corsair hx750 and it never blinked. no game will ever pull as much power as furmark. I also had a 4.7ghz oc on my 2600k and 6 fans running.

now that's not to say it wasn't near 100% peak power, but you can overclock a single 480 to jupiter with a quality 750w unit and have no issues whatsoever.

Two 480s and a CPU overclocked on an HX850 here. Just make sure you get a PSU from a reputable brand.

If you plan on having a load on it all the time, get a bigger PSU for better efficiency if you can. But you can run OC'ed on CPU and GPUs from a 750, 850 if you are going overboard.

I've never had a problem and I fold almost 24/7

Mostly keep my system at stock to minor OC. But at 4GHz and 800/1600 I pull a little less than 600w (from the wall) while folding (on CPU and both GPUs)

Most people are on the right track. Finally lol.

750W for small overclock,
850W for more overclocking.

Just get a reputable brand like Corsair, Seasonic, Antec, Silverstone and you are fine.

I'm running 2500K @ 4.5GHz and a GTX480 @ 831/1025MHz on CM Real Power M620 that has 516W (43A) on 12V+ rail..

I have thrown everything on it from Furmark to 3Dmark 11 and games, and it passed without any problems..

I have also ran a Q9550 @ 3.9GHz w/ GTX480 for a whole year w/o any issues..

For a single GTX480 in your system you would be good with a decent 500W PSU (at least 40A on 12V+ rail) like Seasonic M12 II 520W BRONZE or better..

CHEERS..
