  1. Yes it'll be perfectly fine. As long as it has enough connections though. A HX750 is rather expensive for its price, considering an AX850 which is fully modular is only like $160. An X-850 from Seasonic, top of the line stuff, is also only $149.99 after rebates.

    A 750W power supply would definitely work, however it is always best to run under 80% PSU capacity to maximize PSU longevity. If you already have the 750W PSU, use it, but if you are purchasing a new one, I would go with 850W.
  3. By my count he'd be under 70% of capacity. He'll be find with that unit.
