    See above! I think it is, but best to get your learned opinions!

    Specifically a Corsair HX650w

    Nope you're gonna need 2 1200W power supplies for each card I'm afraid. :pac:

    It should be able to handle it fine, but what else are you running in your system? Will the cards be overclocked? Is your processor overclocked?

    You'll probaly need to get some power adapters to connect everything to the PSU.

    Only 2? I was sure I would need 3! :D

    3 HDD, OCd Core i5 (4Ghz), cards probably at stock.

    @Farcear: Nope, the HX650 comes with 2 PCIe cables each with 2 Plugs on them :pac::pac::pac:

    IF thats the case you best get your self a few of the new ocz 2KW psu's then get a few of them enermax galaxy 1200W jobbies for your hard drives, That cpu is gonna need at least a 700w antec boyo. Best go out and get a generator too, ya know just incase.







    a 500w psu would be fine as long as its got a good solid 12v rail.

    Look basically you need to scrap your current psu and build yourself a nuclear reactor capable of powering a country with at least 10-15 million people.

    You gotta future-proof. You never know he could end up adding another hard drive or plugging in a usb memory stick.

    Zero-point energy. Like in Star Ocean 3. Or something. You'd surely need the energies of a self-contained Big Bang to power that mother! hmmm.gif
