Will a Corsair HX850-V2 be enough for GTX670 3 way SLI??

post #1 of 6
Thread Starter 
I have just purchased a 3rd Asus GTX670 DCU II Top and was wondering on what size PSU i need.
My system is oldish but is as follows:

i7-950 @ 4.2ghz
Rampage III Formula
12GB Corsair Dominator GT
Corsair H100i

Now before everyone jumps on and says "oh you need at least a 1200w psu". Ive done a few benchmarks with the system plugged into a wattmeter and it draws around the 675w on full load. Ive been reading a few forums and most of them say that an 850w is the minimum. The system will be getting an upgrade in the next few months to a 4770k and a Maximus VI Formula so it'll be more power efficient once that happens.

so will a corsair HX850-V2 be fine or are there other options??

I think a quality gold/platinum 850W PSU would suffice.

Yup, you will be absolutely fine smile.gif

Have you already bought the HX850? If not then there are better value options.
Cancel that, you can get $20 MIR at Newegg on the HX850 making it only $129.99

I haven't brought it yet just been looking at a few options. I live in Australia so everything is ridiculously expensive here compared to the US. Can't say I'm not jealous! Lol. Amazon is doing a AX850i for $199 which I thought was a good price and its a help of a psu.

Personally I'd go for the AX860 not the AX860i.

I have the AX760i and the fan on it is a pain, it revs up for about 2 seconds then down again quite often and you can only stop it by setting the fan speed at 40% which you shouldn't have to do really. The Corsair Link software is hit and miss also.

The AX760/860 have a switch that toggles between normal and hybrid mode.

Just my 2 cents.

yea im a little torn now after reading a bit more. A lot of reviews are saying that an 850w is a minimum without overclocking. Can anyone share a bit of light on this as i dont want to undervolt the system.
