Will my PSU support my build?

Im planning to upgrade my GPU to 2 Radeon R9 280x in CF. My current build:

CPU: AMD FX 8350 (Not OC'd)
RAM: Corsair Vengeance 16GB (2 x 8) DDR3
GPU: Geforce GTX 650
MOBO: Gigabyte GA-990FXA-UD3
6 Fans. 3 120mm, 2 120mm LED, and 1 140mm LED

PSU: Corsair RM750. Will the RM750 support both 280x's? I put my specs with 2 Radeon HD 7970 (since they're basically the same GPUs) on the eXtreme power supply calculator, and it said 580W minimum.

  1. It has 4 pcie cables and 750 watts with 80+gold is enough for that configuration. The only thing that bothers me is that the psu is not sli or cf certified(at least i haven't found it yet)
  2. Best answer
    NCIX claims that it is "multi gpu ready".

    750W will do, but you won't have much room for other upgrades.

    Nah, I won't need to upgrade any more for at least a few years. More upgrades would be unnecessary. My CPU is already 4.0GHz Octa core, I have 16GB of memory, and I will have 2 Radeon R9 280x in CF.
