  1. A good quality PSU should handle that unless you are planning to overclock. The recommended minimum wattage for GTX 660 is actually 450W.
  2. For a system using a single GeForce GTX 660 (non-Ti) graphics card NVIDIA specifies a minimum of a 450 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

    For a system using two GeForce GTX 660 (non-Ti) graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 600 Watt or greater power supply that has a maximum combined +12 Volt continuous current rating of 36 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the critical factor.

    Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock you are trying to achieve.

    I am not clued up on those type of things at all (forgive my noobness:D), the power supply is a coolermaster gx-550w.

    It says...

    Input Voltage.... 90-264Vac (Auto Range)

    Input current.... 7A@115Vac, 5@230Vac

    Operation Temperature.... 0~40 degrees celcius (Normal Input Voltage)

    P.S I don't plan on overclocking at all.
  4. thats not a very good model sir, whats ur budget for a ps and what country u live in?

    I live in South Africa and my budget is R850. Which would be about $100 with the current exchange rate.
  6. you use a website , i can probably look for u, if u got a website u can link me too.

    The Cooler Master GX-550W (RS-550-ACAA-D3 / RS-550-ACAA-E3), with its maximum combined +12 Volt continuous current rating of 44 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 660 (non-Ti) graphics card. It is also more than sufficient to power your system configuration with two GeForce GTX 660 (non-Ti) graphics cards in 2-way SLI mode.

    Wow thank you so any power supply similar to those specs should definitely handle it then

    its sufficient but its of bad quality ko, most of cooler masters ps are junk, except a few models tbh.

    best bet here is the

    good 550watt xfx powersupply made by seasonic one of the leading ps companies :D
