Before bringing this article to a close, we'll take a look at power consumption of each of these motherboards. 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.
