ASUS F1A75-V Pro 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 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 ASUS F1A75-V Pro, like all of our A75 systems has an incredibly low idle power consumption. Pulling only 36 Watts at the wall, it had the second lowest draw, second to the ASRock A74 Pro4. Once we started loading up the F1A75-V Pro it was able to maintain the lowest power consumption in our 3DMark Vantage test. When running 3DMark Vantage we saw a peak power consumption of 106 Watts at the wall. Firing up Prime95 Large FFT’s, the ASUS F1A75-V Pro pulled the most power of our systems with 142 Watts at the wall. Though the range we see in Prime 95 is 137-142, so it’s not a huge margin.
