AMD 990FX Mobo Round-Up: Asus, ASRock, Gigabyte

Total System Power Consumption

Before bringing this article to a close, we'll take a look at power consumption of the AMD A8-3850 and some competing platforms. Throughout all of our benchmarking and testing, we monitored how much power this new APU was consuming with a power meter, versus other test systems we used for benchmarks in the previous pages. Our goal was to give you an idea as to how much power each configuration used while idling on the desktop and while under a heavy workload Keep in mind, this is total system power consumption being measured at the outlet and not the the individual CPUs or GPUs alone.

Total System Power Consumption
Tested at the Outlet

All of the motherboards we tested pulled down similar amounts of power while under load, but there were some more notable differences at idle. The ASRock, Gigabyte, and MSI boards idled within 7W of one another. The Asus CrossHair V Formula, however, consumed 9-13 more watts then the other 990FX-based boards while idling. While measurable, those differences can easily be attributed to only slightly higher voltages being used on the Asus board and are not cause for concern.
