I've seen a PSU called 650w Silverpower"Green Power" 80 Plus Certified. It has all the connections I want for a 4890 and such but what I would like to know wether it is good quality at £65? Would it power an E7400, 4890 and a CPU H2O loop comfortably? I'm a great beleiver in things that don;t work hard don;t break (very often). Thanks
