I currently have a 750w supply with a single 60A rail. Im running a core i7 system overclocked at below stock vcore at 3.6. It has 2 SATA Hard Drives and a DVD Burner. I also have a GTX 295 in it. So im fine power wise, my question can i get away with sticking my 9800gtx in there and using it for physx with this supply?
