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.
Benchmark Results: While sitting idle the ASUS Z87-Pro was pulled a bit more than our otherboard with 60 Watts at the wall. Prime95’s power draw showed the ASUS Z87-Pro as the lowest of the three Intel Haswell motherboards and pulled only 155Watts while gaming gave us a high of 236 Watts at the wall.
