    For a system using a single AMD reference design Radeon HD 7950 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 30 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors. Some non-reference models require one 75W 6-pin and one 150W 8-pin PCI Express supplementary power connectors.

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

    Overclocking of the CPU and/or GPU(s) may 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 being attempted.

    The Cooler Master Silent Pro Gold 550W (RS-550-80GA-J3) power supply unit, with its maximum combined +12 Volt continuous current rating of 42 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single AMD reference design Radeon HD 7950 graphics card. This power supply model is not quiet as you would think its name implies.

    No reason to switch from the silent pro 550 to the cx600. If you are going to switch, )which isn't
    necessary), then go with something above "budget level" (the cx series is budget level).
  6. Yes i also said that

    No need to upgrade psu unless u need sli/crossfire
