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 MSI A75MA-G55 has the lowest idle power consumption that was come across my bench, sipping only 37 Watts at idle is pretty darned impressive. Loading up the system with 3DMark Vantage the MSI A75MA-G55 pulled 113 Watts, and Prime95 Large FFT’s gave up 140 Watts at the wall.
