    I'm planning to get another 480 so I can run SLI on my rig but I'm not quite sure if my power supply can handle that, with all the gossip of the 480 requiring a nuclear power plant and all. Can someone fill me in on the facts?

    4 overclocked GTX 480, two XEON W3560 at 4.2Ghz EVGA tested came out to 1200 watts usage at full load.

    Does that answer your question? TBH it would be retarded if a Kw power supply could not run 2 of any GPU.

    I wish my PSU was a kilowatt, but it's only 950.

    you do realize that the difference between a kilowatt and 950watts is just 50watts? :nerd:

    on a serious note a gtx 480 consumes what around 240watts under load? so i guess 950watts would be enough for 2 480s..unless you're overclocking them and the cpu like crazy

    haha, think of it more like "I wish my E8400 was 4GHz, but it's only 3960MHz" :)

    950 Watt is enough to deal with it. Only take care when connecting you pci-e cables.
    Don't connect the cards to the same 12 Rail. keep it in balance.

    Normally a card get 75 Watt from the motherboard. 100 Watt from a 8pins PCI-e cable and 75 Watt from a 6pin PCI-e cable. a total of 250 for the 480 GTX.

    Not to really bring you down or anything, but how the **** did you see EVGA obtain 4 GTX 480's OCed with 2 quad core Xeons at 4.2 at only 1200w. no offence but thats bull****. but still i wanna know because thats awesome if you did.

    Trubritar (if you know who that rich british youtube computer guy is) had 4 gtx 480's and a i7 975 at 4 ghz and reached a max of 1683w. thats a whole 1/4th more with similar specs (except for another one of those Xeons).

    But really. Nuhuh

    u will be good the power supplies that are coming out are very efficient and can take more stress on the rails

    hmmmmm.... I only have 900W PSU and was thinking of getting x2 GTX480's thought it would not be enough my self. Guess I was wrong. I think I will just get one for now and then in a few months get a second...

    I think you are good, there was a list of supported PSUs on nivida official site but I can't seem to find it anymore.

    The answer is a resounding "Yes, but". The 950w PSU should be sufficient for a basic setup plus the two cards. However, you need to consider what other components you use in the system, how much power they draw, and if you overclock them.

    For example, your CPU has a TDP of max 135w. However, if you heavily OC your CPU and push more voltage through it, you may well increase the power draw to 150w-160w. Your soundcard will also draw some power. Do you have a watercooling setup? The pump will draw power. Do you have more than one hdd? A raid+storage set-up draws more power at peak than just one hdd. If you want to overclock/overvolt your 480s, you will see them draw 300w easily.

    All this stuff keeps adding up. I have two watercooling loops and three hdds, so when I went for 2x480s I had to upgrade from my 850w PSU and I looked at kilowatt PSUs only. Ended up buying the Enermax 1250. Maybe the 1050w model would have been OK, but for £30 more, I wasn't going to take any chances.

    Yes, that's Trubitar but it's his rig that matters, I think you will be in a risk but it will still work, go for it or if you can, upgrade to 1200watt for definite safety.

    Isn't one GTX 480 enough for you? lol, lucky, enjoy your rig man.

    Well my corsair 850 runs 2x 470 with good OCs and a 4.0ghz i7 pretty fine with no crashes or whining. So I'd say a 950 will run 2x 480 easily.

    pls dont forget "Capacitor Aging" at least %25 , cause 2x480 will force psu very badly in 6-7 months. So try to include it also.

    i already added more hdd :D and fans :) also 90% system load so i guess it will be fine :)
    and overclocked the CPU :D

    That's going to be a problem, because TX950 is a single rail (78A) PSU. :p

    Yah, it'll be enough (it's even on Nvidia's Dual GTX480 certified PSU list).

    I've got a Corsair TX 850 running my 2 gtx 480s and it barely gets warm when running full load with 850/1700/2100 OC with 1138mV. ( I use a TX 650 to power my MB, CPU, fans, etc.) I'm pretty sure the 850 could power the whole system, but it would be pushing it. The extra 100 watts in your case I think would be sufficient.

    edit: I know it's a lot of power, but I had the tx 650 laying around with the 850 powering my build at the time. I have a HAF 932 with a spot for a second psu so it saved me from having to buy the HX 1000.
