Power Consumption Test
Power draw on the ASRock Z97 Extreme4 is considerably lower than the ASUS offering at idle. Even overclocked, we see it sits only slightly higher. Load numbers see the two ASRock offerings line up with each other, which is again below the ASUS one.
Overclocking, as you'd expect, gives us a decent bump in the overall power draw.
Core Temperature Test
Temperature numbers on the ASRock Z97 Extreme4 are impressive with great looking idle numbers at both stock and overclocked.
Under load, you can see we're in line with the ASUS offering, and overclocking causes a big jump with over 90C being seen at load.
