It's interesting to note the power consumption across all motherboards. Although they are all using the P67 chipset, energy results can fluctuate between manufacturers due to the features and specifications that are integrated. First of all, for the idle tests the system is cold booted into Windows and no additional applications are executed - the watts are noted on the external energy monitor we use and then the system is loaded with 3DMark 11 - watts are again monitored for the duration of the test and the highest rated wattage result is then noted down. Below are the results of this energy test.
As you can see from the graphs the ASUS P8P67 requires more power at idle and load states. Bear in mind though that these results were obtained under the "normal" setting for energy efficiency within the BIOS. You can of course alter this to lower the power consumption. Overall though, the power consumption for the P8P67, whilst being the most demanding doesn't highlight any issues. The difference in watts between the manufacturers isn't worrying.
