hi i jst sent back 2 galaxy gtx460 because even though overclocked they werent as fast as my 5870 cf setup,so im thinking about 2 gtx480 sli,is this enermax revo 950w/1140 peak enough for a i7 4.2/overclocked 2x gtx 480 sli/4 harddrives/6 fans/120x3 rad/pump/1 bluray drive......thx. ps would my triple rad be up to cooling i7 4.2 and 2 gtx480

^ actually 70w
plus Razor Time, we're talking 850w of heat which is a 10C delta even with the 2787rpm Ultra Kaze, which would kind of dismiss the points of water cooling, and if he decided to overclock those 480's then he'd be seeing 1000w of heat, over 1100w if he oc'ed them as far as possible

Which is why I said no. Its pointless having a noisy loop.
I run my 480's off a quad and my cpu is on a separate loop.

Nope at stock, Std Gainward whack Ocuk sell
I believe so, I using a Pc Power & Cooling 750w psu.

Could you overclock it and try again for us say like 800 core ?
Should do that easy .
Im wondering if my Zalman 1000W Psu will cut GTX 480 SLI overclocked.

I wouldn't go that far...
Using 1000rpm fans, the total load (around 800W max) would be dissipated with a 25C delta from air to water. Overclocked, the GPU-core to water delta will be around 15-20C (based on the roundup of GPU blocks on skinnee labs). Assuming cool (~20-25C) air is drawn in from outside, you're looking at a GPU temp of around 65C under load.
Clearly this is less than optimal as far as watercooling goes, but it's a lot better than air cooling. The 1000rpm 120mm fans won't be completely silent, but they will be far, far quieter than the stock coolers under load, and probably quieter than the pair of them at stock.
So the answer is yes - you can cool the three with a single 120.3 radiator so long as you use fans at around 1000rpm or higher, although you're looking at 10C higher temps than if you were to use a dual 120.3 setup.
As for the power issue:
Anandtech shows a maximum draw of 851W at the wall, which translates to around 750W internal power draw, given the efficiency of that PSU. So, this should leave you sufficient room for some decent overclocking, especially as the PSU should be able to go at least some way past its rated maximum (read a suite of reviews to find out roughly how much).
Anyway, in games under 100% GPU load you won't expect quite that power draw. Furmark really does cane the power usage. In crysis anandtech shows 180W smaller power draw than furmark. I know that with my GTX480s you can FEEL the amount of heat coming out when running furmark - it really is incredible. Nothing else is quite in the same league.

ive jst been checking the reviews for my enermax 950w.it can output up to 1140w,so surely il be fine to order my 2 gtx480,i really dont want aything less as i jst sent back my 2 gtx470 as they werent fast enough for me as i like to turn up full eye candy,ive jst seen the msi gtx480 hydrogen,has a fitted waterblock for £398 ,would like 2 of them,so would this be alright duffman

Edit out the name of that retailer sharpish, or the mods will give you a holiday!
As for the block - I'm not familiar with it, but the roundup on skinnee labs showed almost all the GTX480 GPU blocks performing within a couple of degrees of each other. I'm sure it'll be fine...
But yeah... that is a fantastic price for a GTX480 + waterblock...
This forum is paid for by overclockers uk, and understandably they don't want people promoting their competitors, and losing them business.
It's all in the FAQ. Worth a read.
Best of luck with your watercooled setup - I'm hoping to watercool my GTXs fairly soon as well
