Psu, cpu and crossfire setup different readings when doing tests. I'm running fx 8320 at 4.4 on sabertooth 990fx r2.0 with 2 r9 270x toxic in crossfire with corsair cx 750m psu. Now.....I run prime95 and furmark together full screen and what happens is my watts are like 840 (kill a watt installed) with 80 fps and 80% gpu usage and 100% cpu. When I turn all software of and turn it back on I get lag in furmark. 30-60 fps 40-60 % gpu usage and 640 watts and cpu at 100%. What can cause this readings? Bad psu? All help appreciated.
