1000W or 1200W? - Page 2

post #11 of 32
OVERKILL! Both will serve great for you if you have the money. Go with ax1200 if you want a fancy, good, expensive psu. Ax1200 can do 3 to 4 way sli so if you want that then go for it. Personally I say just go with tx850 or tx950. They are good and much cheaper that have enough power for sli gtx 580.

If we are talking V1's then the TX950 is a very good unit, the rest of the TX v1 line is lack luster.

Corsair AX750 will power that rig fine even with SLI 580's, but go for AX850 if you plan on overclocking everything.

Get a corsair AX850 especially if your overclocking your hardware. Probably the best 850w PSU out there with a gold rating as well so you can't go wrong. My friend has one and I just ordered mine. Can't wait to setup this bad boy.

I've been having problems running 2 570's on my 850w... (It won't) I've called Corsair AND EVGA and they said that I'm really pushing my PSU. They recommended a 950w+. But then again people are running 2 on their 850w just fine. Your card will draw about 363w on its own. So you would be at 726w if you did sli not including cpu, ram, fans, etc etc. Get a 1kw or better.

Get a kill-a-watt and factor in efficiency. I doubt your pushing your 850w unit unless there's a fault with it.

That power consumption is full system power use, before efficiency is factored in. It's also not like full potential power draw, it's not prime95 and folding with the 580 at the same time kinda power draw.

I'm pretty sure 500-550w would be enough for just one GTX 580, even if you overclocked stuff. Two 580's would need at least 750w, though.

I've been getting bad info, then!

So, maybe a 1000W just to be safe? As Averywhite was having trouble with his 570's.
