i have a 1250 watt power supply is that enough power to run two of these cards in crossfire

4X150 Watt 8-pin PCI Express power connector is required for CrossFireX™ system. Seems to me your psu is good enough.

I've been running my Sapphire Radeon Vapor-X HD 7970 with a Corsair HX750 750W with no issues.
880981
Yes, i am running 2 of them plus a i7-3770k on 1200W power supply.... no problem

That's more than necessary, with a power supply that massive you can run a tri-fire. But you should always also get a certified power supply for best performance as well.
880983
It should be plenty...look at power connections on this card: I think this one has two 8-pin receptacles. On your power supply, you'll need two 8-pin power connectors for each card.
880984
Yes, that's more than enough. What type of processor and motherboard do you have?
880985
Yes 1250 watts is more than sufficient to power both cards. They both turned on for me with a 1000 watt PSU.keep in mind that these cards require two eight pin PCI-X connectors. Not the standard six pin. To crossfire two cards you will need four separate eight pin connectors.

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.

If you want to crossfire the gpu's then I would not recommend this power supply. If you are only running one gpu then this power supply would definitely suit your needs.

One card requires a 600watt power supply. For saftey purposes the technician suggest you use a 900 watt or higher

It will work just fine. You could run 2 or probably even 3 in crossfire with that psu. 600 is already more than enough. Cpu wont be a problem either

I don't know what your entire system power requirements, but unless you have a ton of extra equipment running you should be fine with 750 watts. I'm running that gpu with a 650 Watt power supply and have zero problems.

It depends on how many other things you have in your system, but 850w should be more than enough. I'm running my card on a 550 W PSU right now. As long as you have the needed power connections off your psu you are golden.
902895
Yes you can. Just make sure to account for other hardware as well. I've seen this card go up to around 120 watts under load.

I have a 100 watt but I crossfire 2 of these cards. I believe you would be fine with a 600 watt

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.

That depends on the graphic card you will be using.650 WATT FOR SINGLE CARD. 2 GRAPHIC CARDS 750 WATT. I RUN A 850 WATT FOR MY RIG POWER TO UPGRADE.

I paired this card with a 400 watt power supply, and that's about as low as power supplies go. So I'd say you're safe with at least 400 watts.

That would definitely be enough for 2 or 3 of these cards in Crossfire. 3 might be pushing it depending on the rest of your rig. I would suggest googling power supply calculator and checking your build if your are going with 3 cards.
1209820
Absolutely. If you're planning on going CrossFire, I'd recommend getting the 800w, but this will run one GPU without issue.

I am running three monitors with this card. that is the max. cross fire yes, with certin other models only

You need a PSU with 2-8 pin and 2-6 pin connectors for Crossfire, One 8 pin and One 6 pin for a single GPU.Yon should use a 850Watt PSU for a Single GPU, and a 1000Watt PSU for 2 GPU's. I have Corsair RM 1000Watt for my 2 GPU's.

I tried crossfire with 2 7870's gigabyte cards with a 850 watt thermaltake power supply and it wouldn't work. I recommend no less than good name brand 1000 watt power supply. However a 1200 watt would optimal.
