Although the products on test today are targeted to the enthusiast overclocking audience they also have encorporated various methods to help reduce power across the board. MSI are proud to display their power saving features, not only on the box but with stickers on the motherboard.
With this in mind we measured power consumption at the wall while obviously removing external devices from the figure, such as the monitor.
The MSI board is the most efficient at idle, however the latest bios from Asrock seems to have improved the results over both idle and load as it was 105/233 before the flash. All of the boards are proficent with power management however and the differences are minor.
