I measured the total system power consumption while running 3DMark's Firestrike using Kill a Watt from the wall and it topped out at about 320 Watts, ran Star Citizen at ultra(basically Crysis 3) and it ran at about the same under 100% load for the GPU and something like 85% for the CPU. Max temp under Furmark for the GPU was 80C and like 50C for the CPU but with fans on automatic and only at ~35-50%. If I add another Sapphire R9 290 Tri-X, will I still be safe power wise if I keep them at stock?
