Asus P8Z77-V LX2 Motherboard Review

We measured the power consumption with the system resting at the Windows 7 desktop, representing idle values.

The power consumption of our entire test system is measured at the wall while loading only the CPU using Prime95's Small FFTs setting. The rest of the system's components were operating in their idle states, hence the increased power consumption values (in comparison to the idle figures) are largely related to the load on the CPU and motherboard power delivery components.

Power consumption was also recorded while playing Battlefield 3, representing gaming values.

In terms of power consumption, the P8Z77-V LX2 sits between Asus' pair of mid-range motherboards. The P8Z77-V features additional controllers, and uses more power accordingly.

The P8Z77-V LK and LX2 boards sport a very similar set of features, but the latter seems to be slightly less efficient. With such a small difference between the power consumption of both motherboards, we are happy to put the variation down to individual samples, not the product designs.
