Total System Power Consumption

Before bringing this article to a close, we'll take a look at power consumption of these motherboard. Throughout all of our benchmarking and testing, we monitored how much power each was consuming with a power meter. 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 motherboards alone.

Total System Power Consumption
Tested at the Outlet



At idle, most of the systems hung around 10W or so of each other, although the diminutive ZOTAC board stood alone at just under the 100W mark. When under a heavy load, however, the field separated quite a bit. The ASUS board topped out at 10W ahead of the next-most power hungy board (the ASRock Z68 Extreme7 Gen3). The ASRock, EVGA, and Gigabyte Z68XP-UD3 motherboards made up one cluster of scores, with all three maxing out within 10W of each other (from 174-184W). The most efficient group, comprised of the MSI, ZOTAC, and Gigabyte Z68XP-UD4 motherboards, were all within just a few watts of each other (from 158-162W).
