How much wattage of PCU for pc?

I'm using pcpartpicker and it says that my estimated wattage is 361W. That's my build if you need to see it. I'm just wondering what PSU I should buy, in terms of watts.

  1. A quality psu within 500-600W.

    Look for the xfx 550 core edition, seasonic s2ii 520/620.
  2. Best answer
    For a system using a single GeForce GTX 670 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 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 most important factor.

    The PSUs recommended by @djangoringo meet the requirements.
  3. A single GTX 670 will max out a 173W. That requires 14.4A on the +12V rail(s). I would feel comfortable with a good quality 550W+ PSU for your system as a minimum. The above mentioned brands are good choices, as are Corsair.
