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 BIOSTAR TPower X79 had the second lowest idle power consumption of any of our boards today. Quietly sipping away the BIOSTAR TPower X79 was pulling only 87 Watts at the wall it idle, second only to the GIGABYTE GA-X79-UD7 which was pulling only 83 Watts. Firing up 3DMark 11 our power consumption goes up to 225 Watts, which is the lowest power consumption by 8 Watts. Loading up our Intel Core i7 3960X with large FFT’s in Prime95 the power draw goes up to 249 Watts. It is still lower than most of our boards, though it was 12 Watts more power than the ECS X79R-AX Black Extreme.
