Power Consumption

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 (both at the default and overclocked system settings). The mainboards are sorted in alphabetical order on the diagrams.

The ASUS P8P67 Deluxe is average in terms of power consumption when working at its default settings. Its results are somewhat worse than average when it is overclocked, yet it doesn't join the ranks of the power-hungriest products.


The P8P67 Deluxe is the top-of-the-line model among ASUS's products based on the Intel P67 Express chipset. It offers everything the company endows its mainboards with, such as a deluxe accessories bundle, a reinforced CPU voltage regulator, an integrated Bluetooth module, eSATA and power eSATA ports, back-panel and front-panel USB 3.0 ports, IEEE1394 (FireWire), and two Gigabit Ethernet ports. ASUS EFI BIOS, a very good implementation of the UEFI standard, should also be commended for its abundant fine-tuning options. I didn’t have much luck overclocking my memory modules, but I did reach the maximum CPU frequency with this mainboard.

ASUS mainboards are usually criticized for being costlier than competitors, but the higher price seems to be justified in this particular case. Indeed, the P8P67 Deluxe costs more than average but it also offers higher quality and more features than you get with a regular mainboard. Besides, the GA-Z68X-UD5-B3 model from Gigabyte, which is comparable to the P8P67 Deluxe in features, turns out to be even more expensive.

And if you don't think you are going to need all the features of the top-of-the-line product, you can easily choose a less advanced model from the numerous LGA1155 models that ASUS offers.
