ASUS ROG Maximus X HERO and ROG STRIX Z370-E Gaming 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. Following are the results of the processor when overclocked on the different motherboards.
Do note that the ASUS ROG Maximus X Hero was running the chip at 5.1 GHz when overclocked and the ASUS ROG STRIX Z370-E Gaming was running the chip at 5.0 GHz when overclocked:
