many thanks

Kinda depends on the rest of your rig, but probably not.
TDP of those cards is 300W, but tests have proven it eats 50W more than an HD5970 (which is also 300W, lol).
So, 350Wx3=1050W for the GPUs. Somehow I doubt you'll be satisfied with 150W for CPU, mobo, ram, etc
Unless you undervolt or something, it's not going to work.
I suggest getting a 2nd PSU if your case allows for that, or maybe just 2 cards?
Yeah what jcool said. Either 1500W or dual psu setup.

"For anyone running a 2-Way SLI GTX 480 setup, we would suggest no less than a 800 watt power supply of good quality"
soo im not over clocking anything and they also said that the board is actually 250 watts = ill have more power left
bump
I'm calling BS on those numbers. Let me just give you a little comparison my dual gtx295 setup when running furmark burns roughly 1050W. That is with an i7 @ 4.2ghz and stock gpu clocks. Here is a review that shows i7 @ stock and 2-way sli using 730W. Adding an additional card was 282W, so with some math thats 1012W stock with a pretty bare system. With a decent i7 OC your system will be peaking at roughly 1200W.

Yeah you need 1500W PSU and not a watt less.
All I'm going to say is that if it was me I'd have at least a top 1200w multi rail just for the 3 vid cards and a separate appropriate sized psu for the rest of the system.

The silverstone 1500 watt psu is soild, and what I am personally using for a tri sli gtx 480 system I am building.
A beefy power supply for you

but don't forget Antec 1200W and Enermax 1250
I have the strider 1500w and I am sure this PSU would be enough for your needs!

Frist off i would never buy a mult. rail power supply . I already when down that road once and learn my lesson . There one power supply maker i like that PC Power & Cooling there 1200w power supply has a 90a
single rail it also look to have the right PCIe plugs for 3 video card set up 3x6 and 3x6+2 plugs to run one 6 + 8 plug 3 time on the video cards here the link http://www.newegg.com/Product/Produc...82E16817703020

How about NVIDIA's official list: http://www.slizone.com/object/slizone_build_psu.html
it has a 100 amp rail, not a 90, peak at 115 amps.
but it is loud as hell, unless you do like I did and cut a 120mm hole on top, and mount a nice quiet fan, and replace the loud Delta 80 mm with a quiet fan, then it is a powerful, cool, quiet power supply.
the 1500 Strider seems good, it keeps fairly cool, is quiet, and seems stable, but it is on mu wifes rig and maxes out around 1300-1350 watts at the plug.
either would work for tri GTX 480's, as long as everything was not OC'ed to the nutz.

This should be enough

Well looking at what he trying to do, that 3 GTX480 in one case just the fans off the three video cards are going to drown out the power supply fan let alone all the case fans he going to need to keep it all cool .If he gose with water cooling he going to need a radiator off a mack truck a pool for a tank and a pool pump to move enought water through the 3 video cards to keep them kool and the pump fans for that are going to make a bunch of noise .Noise is what happen when you use the bigest power hog of a video card ever made by man that also makes the most heat every made on top of all that .If you want quiet you use ATI video card you want noise you use the new 400 video card made by Nvidia . He want to know what power supply would get the job done and the PC Power & cooling power supply would do it. Lests face this rig is not going to be quiet .

if you dont oc... a good 1200W psu or maybe even 1000W psu might be enough...
but that would probably overload the psu when running furmark or folding at home and the psu would burn out after a while...
to be on the safe side id def recommend a good 1200W psu or 1500W psu... silverstone actually tests lots of highend vgas on their psus... they had a system running 2 gtx295 cards and 2 9800gx2 cards all running folding at home last computex... so if i were you, id contact silverstone or other psu makers and ask them what psu they recommend you...
I don't understand why you think this kind of build has to be loud?
While my rig was designed to handle 3 GTX 480's, I could not wait any longer, so I went with 3 5870's, I know the power draw/heat is more with the Nvidia cards, but I believe my rig would handle them fine. The only audible components on my gaming rig is the water pumps, and they are in their own compartment, heavily sound insulated.. overall a very quiet PC.

ok guyz what i saw from trubs lastest vid his system maxes out at 1150 watts
he was running two psus BUT the sum of the 2 = less than 1150 (running a ws setup 980x oced to 4.4 ghz and 3 gtx 480 at 801mhz
what about the evga psu for the SR2, that should be out soon right

Link me the video I'm curious to see the results, then I'll suggest a good psu for you. Whats your price limit?
