  1. If you can buy it today, get http://www.newegg.com/Product/Product.aspx?Item=N82E16817182200 .

    630w is more than enough and 750w is overkill.

    You could run that system with a good 500w.
  2. Best answer
    For a system using a single Radeon HD 7850 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 26 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

    For a system using two Radeon HD 7850 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 600 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 36 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!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important factor.

    Overclocking of the CPU and/or GPU(s) will require an additional increase to the combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. If you're planning on a CPU overclock that is less than 4.6 GHz you shouldn't need an additional increase to the combined +12 Volt continuous current ratings mentioned above.

    The Corsair Enthusiast Series TX750 V2 (CMPSU-750TXV2), with its combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Radeon HD 7850 or even with two Radeon HD 7850 graphics cards in 2-way CrossFire mode. There is more than sufficient reserve capacity available to handle any overclocking of the CPU and GPU(s) that you may want to attempt. The 5-Year Warranty is better than industry standard.
