Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. The systems ran with the power supplies, case fans, video cards and hard drives. To measure idle usage, we ran the system at idle for one hour on the desktop with no screen saver and took the measurement. For load measurements, Prime95’s in-place large FFT’s was run on all cores to make sure each and every processor was at 100% load for maximum power consumption and heat. We also ran Furmark 1.8 at 1280×1024 to put a full load on the graphics card. All systems were tested using as identical hardware.
The ASRock X58 Extreme3 had a much lower draw at idle than the EVGA board did. Both system boards were very nearly the same draw under a full load.
