Best PSU for my Custom Rig

Hey -- I need some help. I'll be running an old alienware outfitted with a new mobo, gpu, cpu, and ram (specs below). What is the best PSU that I can get, for the money? I can't afford any really-high-end psus, as I would rather waste my budget on the other parts.




and I'm not sure whether to buy the Radeon HD 6970 or GTX 570 GPU... I've been leaning towards the 6970 but the 570 is cheaper, any thoughts on that would also be appreciated, if not necessary (I'm mainly going to be playing games like BC2 and Metro)

I think that a good 600w PSU would power this, but can anyone tell me which one would be best? Thanks so much.

  1. The performance between the 570 and 6970 is fairly minor. My personal prefrence is Nvidia cards so id be leaning towards the 570, however neither will disapoint.

    For the 6970:
    550 Watt or greater power supply with one 150W 8-pin PCI Express® power connector and one 75W 6-pin PCI Express® power connector recommended

    For the GTX 570:
    Minimum Recommended System Power 550 W

    ^ Information taken from manufacturers website.

    So yes, any good 600w Power Supply would be perfect.
    Leading brands; Corsair, Antec, XFX, OCZ are a few to look at.
  2. Best answer
    Both HD6970 and GTX570 are great cards with similar performance. The cheapest around 600watt PSU I would buy Antec EA650
    Or this one if you want to deal with MIR
    Either is plenty for your setup with a single GPU!
  3. Just make sure what you get is 80+ certified and made by Enermax and you can't go wrong.

  4. I would get the Antec EarthWatts as mentioned before in Rolli 59's reply

    Also, if you specify a definite range of prices, the community will be able to help you further.
  5. $59.99 definitely works for me, thanks!
