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 (at the wall) is measured while loading only the CPU using Prime95′s in-place large 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.
Operating under Intel’s low power states at idle, Gigabyte’s Z97X-UD5H-BK delivers solid power consumption numbers for a controller-heavy motherboard. Overclocked figures help to speak for the efficiency of Gigabyte’s “durable” power delivery system.
