Power Consumption

Under load the MSI X58 Pro-E consumes ~30 watts less than the Asus P6T Deluxe, which is very good though it is considerably lighter on features as well.

When at idle the board used roughly 10 watts less than the P6T Deluxe. Overclocking the Core i7 processor to 4GHz threw operating efficiency out the window as you can imagine. Under load the overclocked system consumed an incredible 375 watts.
