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 were run on all cores to make sure each and every processor was at 100% load for maximum power consumption and heat. Curious about real world scenarios, we decided to drop Furmark and ran 3DMark 11 on the performance preset and took the maximum power consumption during the first GPU test.
When sitting Idle the ASRock Fatal1ty Professional P67 motherboard pulled only 77 Watts at the wall. Loading up the Intel Core i7 2500K with Prime95’s large FFT’s the consumption increased to 156 Watts at the wall is is lower than most of the Intel P67 motherboards we have tested. Firing up Futuremark 3DMark 11 for a more realistic power draw we saw the power consumption peak at 212 Watts at the wall. Interestingly enough this was higher than many of the boards.
