Intel Core i7-6700K And Z170 Chipset Review: Skylake For Enthusiasts

Power Consumption Testing

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


The Intel Core i7-6700K was relatively power efficient. At idle, the platform used significantly less power than the Haswell-based Core i7-4790K. Under load, however, the Core i7-6700K used slightly more power than its predecessor.  We haven't had the chance to experiment with many Z170-based motherboards, however, so we're unclear whether the delta we see here is strictly because of the CPU, which no longer has FIVR, or the platform as a whole.

We should also note that we monitored power consumption while overclocked to 4.6GHz as well, and saw only a marginal increase in power consumption. While overclocked, the platform's power peaked at only 152W.
