I'll have a FX-8320, and 2 R9 280x, all three overclocked. The graphics cards not much, the cpu maybe 4.5. Will that psu be enough, especially when they are running full load mining? If not, do you have any suggestions? I was looking at the SeaSonic Platinum 860w, but people were talking about coil whine.
