Asus GTX 680 sli and AX750

Would an ax 750 be powerful enough to power 2 asus gtx680s in sli, an i5-3570k overclocked to 4.2 ghz, 16 gb of corsair vengeance 1600mhz ram 1.5v, 3 coolermaster sickleflows 120mm, an antek big boy 200mm, and a cooler master v6gt? If a 750 cannot do it, I can easily fit a ax850 into my budget. If an ax850 cannot do sli asus 680 oc, could a ax750 do 1 asus gtx680 oc? I do not plan to do 2 asus 680s right now but would like being able to do it in the future without buying a new psu.

EDIT: sorry by asus gtx 680 I mean this one:

850 could with a little headroom, 750 might cut it a little close, but I think you can go to Nvidia's website and they'll tell you SLI recommendations.

But this is using more power than the stock card. I'll go with 850 anyways just in case.

I would think that its more than enough power to do so.


edit: user data

heres a quote from one of them:

Quote:
I use the AX750 for my 680 sli. The highest power draw I've seen is 648w (at the wall and not taking the psu's 87% efficiency into account) with 3d11 with the 680s at 130-155-400 OC and my cpu is OC at 4.6ghz and a bunch of external HDDs and other crap. Gaming is in the 500s, so 1200 will definitely be enough, but definitely not necessary. This is one of the reasons I waited for the 680s - less power draw and not requiring a new PSU. They draw less than 570 sli.

I would say it should be enough, the AX750 is pretty solid.

Yeah but my cpu cooler uses like 200 watts so i'll go with a ax850 just to be safe. Its only $20 more, so why not? Im just afraid of upgrading or overclocking in the future when my psu cant handle it.

CPU cooler uses 200W?

Anyway both are good options, it doesnt really matter.

well the tdp is 200w but thats at max load. But max load is 93 cfm which is a lot to cool a cpu, even overlocked. So It will use less.

Its not like getting a bigger power supply is worse or something. Go for it if you have the cash.

How about the "Corsair CMPSU-700GEU GS700" ?
would it run the same spaces ?
