    I ran this through a wattage calculator from thermaltake and it the wattage should be fine. I had to make some assumptions about ram and other drives you had, but a 750 should be plenty. From what I have found, running 2 of those cards is a power draw of about 260 watts. The calculator based on what I entered into it gave me a minimum of about 434watts, so your 750 should work.

    Here is a link to the calculator if you want to check it out :
