No it really didn't. I think I mentioned here elsewhere in a comment but I use an Intel Core-i7 6700 "non K": so the version that is not meant to be overclocked and which Intel rates as having a max TDP of 65W. And this would be with the four cores running. I don't know the TDP / power consumption when it's turbo-boosting at 3.9 or 4.0 Ghz (when one or two cores are at full speed on the 6700, it goes from 3.4 to 3.9 or 4.0 on these cores).

Basically I like my workstation to be quiet. Really very quiet: as in I can only hear it if I put my ear on the tower. So I never have ultra power hungry CPUs. I don't game so no GPU besides the integrated one. A M.2 SSD which consumes next to nothing.

Power bill probably did increase a bit but honestly it was lost in the noise: I definitely didn't notice anything : )
