Aerocool PSUs are not really worth it as they're classed as a tier 4 power supply maker (They aren't really top quality and that trusted)
If you ever do plan on going SLI for your computer then I would get the Corsair CX750w, or any XFX or Seasonic equivalent.
If you don't plan on SLIing and just want to stick to a single GPU then i'd get the Corsair CX500 or any XFX or Seasonic equivalent.
