ultra x-connect 750 watt powersupply
just stick with what you have, if you feel it not p to the job get at 700w with a good name with it like, coolermaster, Hiperpower, enermax, akasa... but i would just see how your system handels what your getting.
PC Power and Cooling, and Corsair make the absolute best power supplies for the 550-800 wattage ranges, the PC Power and cooling being the absolute best and the Corair being the best bang for your buck. If I remember right the Ultra X-connect series sucks, and I would not trust any Ultra power supply except the X3, and thats still pushing it.
