I'm thinking on getting this card( 2 of them) for my new build. Do I have to install CrossFireX and will a 1500w PSU power the both of them

these cards no longer use crossfire cable, they do crossfire through PCI lanes, and I recall a review using a 4770k OC and two of these monsters on a corsair 1500w and it wasn't enough on some games at 4k, so you may need more depending on the resolution you will play on. And dont forget to get a beefy surge protector

Not sure how well CrossFireX will scale across 4 GPUs. I personally have a 1200w PSU for one of these cards. According to Tom's Hardware the card only draws 450w at full load. Can't link the article at the moment on my mobile.

yes, you must install a 1500w psu for both graphics card, then youll have a quadfire installation, so it requires more power, greetings and hace a nice day

It is also possible that one 1500W PSU will work, but problem can be with motherboard - unable to handle a brief decrease in voltage.

Depends on the rest of your hardware. This card uses 150w, you will have to calculate the rest on your own. Minimum recommended is 500w.

Yes I have a 500watt power supply and it runs great unlessential you are try to do crossfire then I would get a higher watt power supply

I can tell you this, and it might not directly answer your question:the powersupply is not designed to be very powerful, it was made to save on power costs. It is also non-standard, so you need to take that into account.ALSO,It has 2 displayports, out of the box. although I haven't tried hooking up 2 at the same time... so you may just need one additional card

300 watts is insufficient for this card. I'd recommend a 500w of real power. Don't buy a cheap brand. The longevity and safety of your entire PC rests in the PSUs hand.

One of these draws 250 W according to Nvidia so x2 = 500. You also need to account for your CPU MoBo and other things so I would go for something ratted with 700+ watts.I recomend this SilverStone ATX12V/EPS12V 750W Silver PFC Power Supply ST75F-P (Black) or this if you want silence http://www.newegg.com/Product/Product.aspx?Item=N82E16817151087

I would like to turn you away from this PSU; I ran two GTX cards in SLI and this power supply didn't hold up too well. I recommend NOT getting this power supply for crossfire. It's not power efficient, it doesn't have the best stable voltage, and lastly 600 watts is a little low for multiple GPUs. Also when I was doing SLI on this I swear it almost overheated and cooked to death. You should get a bronze-rated Corsair like the CX750 instead. I upgraded from this PSU to the HX750, at the time I bought it, it was around $120. Best power supply I think money can buy that isn't overkill. Gold rated, modular, and the fan doesn't run at all on idle use. That's another thing, I had noise issues with this PSU. Do yourself a favor, get a good power supply and avoid this. I don't want to call it junk, it was pretty decent, but honestly I wish I went with something better to begin with. I think Corsair is the best name for PSUs. Either them or Cooler Master also has some nice models.

It depends on what you're really planning to run for your video card. I use this card with two Radeon HD 7790 1GB cards in CrossfireX and it runs fine. But if you were to go any higher than that with video cards, you're going to want a bigger PSU.

Dear friend, I strongly recommend at least 300-350 watts per video card. So just for the cards you would need 900-1050 watts. You still need some more power to the rest of the system. Get that 1600 psu ASAP...

sure you need them both, AMD recommends a 500watts power supply or greater to run this card so if i where you i wont do any risk
1492014
Single card you can get away with a 750, the card draws about 350-375 watt sunder load, according to a comparison to the 970 and 980 cards, I just was reading today. I personally overshoot to make sure my PSU isn't working very hard. Example I have a dual card setup and i use a 1300w PSU EVGA.

Will depend by other resources you have in your computer like coolers.In my computer I use a XFX 1050W , but I have a 300W CPU cooler. I recomend at last 550W REAL if you dont have any cooler with high demand. But if you will buy a new power supply I recomend go with at last 850W Real. I like the XFX full modular. They have awesome power supplies

Hey. As per specification each of these beauties has a 250W power consumption.So it recommendable to get a 1200w or more PSU for three of this kind. You'll be more than well served with a 1600w PSU for a 3 WAY SLI.Cheers!.http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-780/specifications

AMD has moved to XDMA CrossFire, what this means is that all communication between crossfired cards occurs over the PCIE bus as opposed to seperate connectors. This has resulted in fewer frame time variances and less stuttering in crossfire configs.In short, Yes. Although you may want a beefy PSU.

Late answer, so I hope that you haven't had any problems. At full load, this card can consume up to 350W. I wouldn't go less than 750 for a PSU. If you plan on an OC, I'd go even higher. That being said, my CPU, GPU, and RAM are all OC'd. I've also got four HDD and one SSD, five case fans, and a 1050W Corsair. If you're considering spending this kind of money, I'd feel better knowing that the PSU voltage isn't going off course due to an overload, or that the PSU killed itself without taking casualties (fingers crossed).

To completely overclock this card you don't need any extra power. The Psu powers EVERYTHING in your computer not just your GPU, Go to pcpartpicker.com and place what you want in your computer or if you're upgrading place what you have and this card and it'll give you estimates on psu power needed.
