    Here are your options:

    Corsair CX600
    SeaSonic S12II 520
    SeaSonic G 550
    XFX Pro Series 550W
    Antec High Current Gamer 620M
    Corsair TX650 V2
    SeaSonic S12II 620
    XFX Core Edition 650

    Suitable for normal overclocks and 600W+ units can even handle 2 GTX 660ti (though they may not have enough PCIe connectors)

    Can you tell me, for my situation, which is the best?
  4. It depends really. If you don't see yourself going SLI in the short term, 500-550W is enough (and even for higher end cards like the GTX680 or HD7970). The best performing unit in the list above is the SeaSonic G550 but it's a little bit expensive for a 550W unit but quite reasonable considering it's 80+ Gold efficiency, semi-modular interface, tight voltage regulation and great ripple suppression. If you have the money, I can wholeheartedly recommend it. If you'd like to save a couple bucks, the XFX 550W or SeaSonic 520 or Corsair CX600 are good options as well
