I would choose a higher-quality PSU - the CX500 I believe is Corsair's bottom of the barrel, I'd be willing to bet it doesn't use 100% Japanese parts. I'd recommend reading some reviews on it first if your dead-set on this PSU. I always prefer to overspend on a quality PSU, since having a really good one can save a lot of headaches. A good one is Seasonic SS-760XP2. You may not need 760 watts now, depending on if you OC, but it leaves room for expansion, and even if you only use half the capacity, the less "work" the PSU has to do, so much the better.
