Best graphics card that runs on 550 Watts powers suply or less

I have a ATI 7770 and a GTX 660-TI both runs smoothly on my 550 watts power supply. But I need a new card. So my question is, what is the best Graphics card I can get that runs on the same wattage as the 7770 or the 660 or even less. I don't think i can run any higher then 300 watts graphics cards or am i wrong?

  2. You might want to tells us your exact model of powersupply, there is a big difference between a Seasonic 45amp single rail 550watter, and a generic psu with 2 rails @ 18amps, and only one with PCI-e connectors.

    That powersupply isn't any good, I'd replace it before doing anything else. That said it's got about 16 amps on each of the 12v rails. So that's 192 watts. Minus about 20% to be on the safe side with that PSU, and you've got around 150 watts or so... Looking at the actual power consumption charts 150 watts is about what a gtx 660ti pulls, do that's your best card... (which you already own.)

    Go out and buy a nice PSU (at least 45amps on a single 12 volt rail), I hear xfx has some good deals, as does corsair, evga, and rosewill. Here's a good one:
