    You should go to a site that has a PSU power calculator. (Newegg has one if you are shopping on their site, as does Thermaltake http://www.thermaltake.outervision.com/)

    Enter everything from your computer in there are see what the minimum power is you need for your computer. After you know that, then you can start actually looking for a PSU. As Susendeep said, you can't base it solely on the GPU, though, that can dictate the minimum power.

    Deciding the PSU only on the basis of thermal and power specs of GPU is not so accurate as pointed out by
    ko888 (a Tom's hardware forum user) -

    " For a system using a single GeForce GTX 650 Ti graphics card NVIDIA specifies a minimum of a 400 Watt or greater power supply that has a combined +12 Volt continuous current rating of 20 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

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

    Other components of PC wold also require power.Hence,a good power supply from Cosair,Antec would be good.

    I would recommend Cosair's CX series for normal usage and GS series for gaming usage.

    The recommended power supply for that card is 400 watts; however, you never want to have a load more than 80% of your power supply capacity running. So you need to take in account your processor, hard drives, fans, etc and do a rough estimate of what you are consuming now. You can find ballpark numbers for these devices

      Accidently submitted -.-

      In addition, you need to decide if you want to plan for future upgrades as well. If you are planning to do SLI, you will need a higher power supply, unless you don't mind buying another power supply again.

      You want a reputable manufacturer. While not glamorous, a well built power supply is critical to keep everything running correctly. Personally, I use:

      However, I had need to have a quiet power supply, as my case was noisy enough. Provide what specs you have now and that will help in selection, as well as budget.
