Intel Z68 Express with Smart Response Technology

Total System Power Consumption

Throughout all of our benchmarking and testing, we also monitored how much power our test systems consumed using a power meter. Our goal was to give you all an idea as to how much power each configuration used while idling and while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the processors alone.

Total System Power Consumption
Tested at the Outlet

Our tests showed the newer Z68 Express based motherboards consuming slightly more power than the P67 Express, under both idle and load conditions. The Gigabyte motherboard used the most power of the three Z68s we tested, followed by Asus, and then MSI--although the Asus board's idle power was lower than the MSI boards. The differences here are relatively small, however. Slight changes in voltage from board to board can easily account for the deltas in the graph above. For all intents and purposes, the Z68 Express consumes roughly the same power as the P67 Express.
