ASRock Z77 Extreme6 Motherboard w/ Intel i7-3770K Review

We measured the power consumption of our entire test system at the wall while loading the CPU using Prime95. We recorded results with the system at reference clock speeds and when overclocked to 4.7 GHz.

In this test we can see how the die shrink to 22nm with the latest Ivy Bridge CPUs has a positive effect on power consumption. Under load, the 3770K consumed 23W less than the 2700K and 16W less when overclocked.
