GTX 480 PSU ? - Page 2

post #11 of 37
850w will be plenty. I run SLI GTX 580, which has very similar power consumption, on a 750w with a pretty large OC on the CPU and it works fine.

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)

750W is more than sufficient to run a GTX480 on its own. For SLI i would recommend an 850W minimum, perhaps higher if you'll be doing heavy overclocking.

Now you're making me think twice biggrin.gif

I have GTX480 in SLI. But I'm thinking your CPU takes more Watts than mine thinking.gif

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.

You can check this page out here and it shows what kind of wattage those things can pull. Seems to be quite a lot under load from furmark tongue.gif

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'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..

It's strange but my cards never pull that much lachen.gif

395

Right now my Rig is at idle at 160Watts from the wall! And yet "Tom's" thinks my two cards alone should be pulling 292Watts rolleyes.gif
