I have 6GB of RAM and an i5 760 if that helps

  1. For a system using a single HD 7870 graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 27 Amps or greater and have at least two 6-pin PCI Express supplementary power connectors.

    So the cx500 v2 meets these requirments
    If you wanted to play it safe, the cx 600 is the same price on amazon

    Or for just a little more you could get a modular antec.

  2. It will be pushing it but yes it would work
  3. Would the Silverstone 500w STF50F-ES230 be better that corsair has some bad reviews
  4. The corsair is a fine psu, a lot of bad reviews come from the people who got one DoA. Which is a risk your taking when buying any computer electronics. if you are trying to get one in that budget range the corsair is your best bet, unless you want to spend more. I wouldn't buy silverstone personally.

    I would follow this posters advice and grab the CX600 for that price, it is also bronze certified so you know itll have solid efficiency and you will get the power you pay for.
  6. For a system using a single AMD reference design Radeon HD 7870 GHz Edition 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 28 Amps or greater and have at least two 6-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) 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 being attempted.

    The Corsair Builder Series CX500 (SKU# 75-001667 / CP-9020047), with its maximum combined +12 Volt continuous current rating of 38 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7870 GHz Edition graphics card.
