Don't run that. that is not a good power supply, and that system will tax it severely. when that i7 jumps into full load it can draw huge amounts of power well over TDP, and that card can draw a good amount of power. I would aim for around a 600 watt or higher 80 PLUS BRONZE or better power supply from EVGA, XFX, Corsair ( RM, AXi HX, NOT VS OR CX OR CXM), seasonic, or superflower.
