I am using a corsair gs600 PSU, it has a 48 amp rating on a single 12v rail. I bought it brand new at best buy a month or so ago and it has been working just fine so far. it is powering my core I5 2310 at stock speeds along with one optical one HDD 8 gig DDR3 and my 4870 with a small OC. Can this PSU handle a dual gpu gtx 295?

Nvidia says 680W minimum. It eats ~415W on full load. I have a 750W Corsair TX750 running my GTX295 and it seems to work well.

Uggghhh, that's a tough one. 700w is kind of the safe zone for a dual chip card.

yeah that's what I'm feeling, a local guy has one for sale but I'm not gonna upgrade my PSU for an old card. probably just gonna pass.

When I asked what would be comparable to a GTX295, people said I'd have to get a 570. It's really not a bad card. It doesn't have the memory (for whatever reason SLI doesn't use both sides of memory?) or DX11 though.

It really performs quite well.

Good choice, you don't want to mess with the microstutter, power consumption, or lack of DX 11.

if lower power consumption is your motivation, get a new Radeon card. they have lower peak power consumption than nVidias offerings ATM.

I ran an overclocked i7 and a overclocked 4870 X2 and 4870 1 gig card trouble free on a 750 psu for 6 months

Your CPU is pretty miserly, and your PSU has plenty of amps. You should be good.

Does anyone know if, while that power supply may work for quite a while, will running that video card on it lessen the life span with such a large draw coming from just the video card?

I only had the micro stutter problem on "true" SLI, as in 2 cards in two PCI-E slots, configurations. The cards that were two cards on one PCI-E slot I have never seen micro-stutter. At least in my experience.

OP 600 might be enough but its going to be taxing on that PSU. It will burn out sooner than later.

Any time you run something harder and it runs hotter than it would under a lighter load it will not last as long, but a lot of the time people upgrade before that becomes a problem....you could always buy a new one. PSU aren’t too expensive.

For 175 he is offering a 850w black widow tt PSU and the gtx 295 its a good price but for that much i'd rather keep my PSU and get a 6870.
