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 identical hardware.
Idle power consumption of the ASRock 890GX Extreme4 and the ASRock 890FX Deluxe4 is lower than that of any of our other system boards. The load power consumption of our ASRock motherboards falls in right at the halfway point of all of our boards.
