Z77 OC Motherboard Shootout - MSI vs ASRock

Total System Power Consumption

Before get to the final overclocking showdown, we'd also like to talk a bit about power consumption. Throughout all of our benchmarking and testing, we monitored how much power each of our test mainboards was consuming with a power meter, and compared them to the reference systems used throughout our benchmark tests.

Total System Power Consumption
Tested at the Outlet
Our goal was to give you an idea as to how much power each configuration used while idling at the Windows desktop and while under a heavy CPU workload. Keep in mind, this is total system power consumption being measured at the outlet and not the the individual power consumption of the motherboards alone.

The power consumption numbers offer an interesting surprise; these two motherboards are pulling almost exactly the same amount of juice under load. True, the idle ASRock board drinks a little more at idle, but 6W isn't much of a difference.
