We performed our power consumption measurements using an Extech Power Analyzer 380803. This device is connected before the PSU and measures the power draw of the entire system (without the monitor), including the power loss that occurs in the PSU itself. In the idle mode we start the system up and wait until it stops accessing the hard disk. Then we use LinX to load the CPU. For a more illustrative picture there are graphs that show how the computer’s power consumption grows up depending on the number of active execution threads in LinX. The mainboards are sorted in alphabetical order on the diagrams.
Like in the performance tests, the mainboards do not differ much in terms of power consumption, yet we can note that the ASUS products need somewhat more than the average amount of power. The MSI disables power-saving technologies when overclocked, but the ASUS mainboards are comparable to it in this test. This seems to be the only disappointing fact we could find about the ASUS products in this test session.
Now that we've tested a number of different LGA1155 mainboards with different chipsets and from different brands, we are quite sure that the ASUS ones are among the best. They come in nice-looking boxes with good accessories, are very well made and have convenient component layouts. With their handy PCB design and user-friendly EFI BIOS, these mainboards support cutting-edge technologies and are overall up to today's requirements. Moreover, ASUS offers a very wide product variety allowing you to find the model for your specific requirements and needs. We wouldn't say that ASUS mainboards are superior to the competition in everything, but they are surely among the leaders when it comes to the winning combination of features, performance and other factors.
