GTX 480 PSU ?

post #1 of 37
Thread Starter 
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.

Correct,

And KEEP in mind that that is power from the wall and not inside. Take efficiency into account and the value is much less.

Change of plans everyone, just got another 480 in TigerDirect for $219 tongue.gif So..I'm going to SLI. Will a 1000w psu be enough? Or should I go conservative with a 1200w?

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.

Really just a 850w? Even if I plan on OC'ing the cpu? Hmmm!
