ASRock Z370 Professional Gaming i7 Motherboard - Power Consumption Tests

The Coffee Lake architecture is meant to improve overall system power consumption and add to the efficiency. In the case of the 8th Gen CPUs, we are looking at refined 14nm++ process which allows Intel to gain improved clock speeds and increase the number of cores with in the same power envelope.

With the frequency bump, the new chips do end up with higher power consumption both in idle and load states. The Intel Core i7-8700K when overclocked, breaches the 400W barrier although surprisingly, it's not as intensive when compared with Core-X or Kaby Lake processors. The Core i5-8600K remains under 400W with an overclock of 5.1 GHz which is good to see while the Core i5-8400 remains at a super steady 336W (full system power consumption) even when the system is stressed under full load.
