Since power consumption is a big deal these days, we ran some simple power consumption tests on our test beds. The systems ran with identical power supplies, Solid-Sate Drives, Memory kits and motherboards from the same company. 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 other test scenarios, we decided to 3DMark Vantage the performance preset and took the maximum power consumption during the first GPU test.
Benchmark Results: The GIGABYTE A75-UD4H pulls more power across all of our tests. Sitting idle the A75-UD4H pulls 43 Watts at the wall, while the lowest power consumption at idle that we have seen is the ASRock A75 Pro4 which pulls only 34 Watts. Firing up Prime95 Large FFT’s the GIGABYTE A75-UD4H pulls14 Watts more than the next lowest board and 19 Watts more than the lowest board. When we fired up 3DMark Vantage to simulate gaming performance, the GIGABYTE Socket FM1 motherboard continued to pull the most power with 118 Watts.
