if i do crossfire will1250 be enough power

It depends.. If you're running a custom liquid cooling loop, two CPUS, a couple hundred gigs of ram, and about 50 fans that second MIGHT put you over. If you're running any normal rig then you're fine. Though you may consider the new 290x at this point, just get a non-reference model with great cooling.

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.

That's more then enough more! You could run triple crossfire if you wanted to!

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

if your power supply is a 500W or above you will be able to power the card. Provided the rest of your system isn't low end or super dirt old, you shouldn't be bottlenecked or have to worry about hardware compatability.If you mean software wise like drivers, well Nvidia cards like to play well with eachother so having an Nvidia card in there and swapping to another Nvidia should be fine if you do not wish to reload your OS.

I am sorry I do not know the answer to your question. I will say I am liking this card and will end up getting another one to crossfire. Good luck.

Yes i have a 750W PSU and it should be even enough for a crossfire with two of these GPUs

You may need to upgrade your power supply. The chip manufacturer (AMD) specifies the following: PCI Express based PC is required with one X16 lane graphics slot available on the motherboard 500W (or greater) power supply with one 75W 6-pin PCI Express power connector recommended7 600W power supply (or greater) with two 75W 6-pin PCI Express power connectors recommended for AMD CrossFire technology. Certified power supplies are recommended. Refer to http://ati.amd.com/certifiedPSU for a list of Certified products Minimum 4GB of system memory 8GB (or more) of system memory recommended for AMD CrossFire technology.

Probably, depends on what else is in the system and the CPU power draw you have

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.

it depends on the rest of your system but this GPU isn't a power hungry . only uses 65watts max so it do'll find on a 300 watt PUS :D

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.

Well, I've seen power draw benchmarks of 2 Crossfire 290xs range from around 600-750. So I would would say a PSU thats a tad over 1000 W total. Don't cheap out on your PSU either, get something with a reputable OEM. Would hate to see your cards go up in smoke.

Yes it will. If you are going to use powerful graphic cards, the 725 watt supply would be best.

Yes, 500 watts should be more than enough. Make sure that you use a decent brand name PSU.As mentioned below, if you are running a massive overclock on the CPU or try to overclock the GPU then you might run into some issues. On stock clocks and with a normal build you should be absolutely fine.

Cannot help you with an answer to that, don't want to smoke your computer.You might go to the Nvidia site and see what the power requirements are andthen check the motherboard web site to see what they say. Also see if Nivida hasan 800 number you can call. Sorry that I can't be of more help to you.

It should be well more than enough to cover it. That combination, even overclocked, should use around 500W of power, taking into account everything you'll have in your system.
