ASUS Rampage IV Extreme Motherboard ReviewWed, Jan 04, 2012 - 12:00 AM
System Power Consumption
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: The ASUS Rampage IV Extreme pulled more power across all of our testing scenarios than the GIGABYTE GA-X79-UD7 did. It was a consistent 21-22 Watts higher than the UD7 across all of the tests.
