I wonder how much more you pay in electricity costs over a Kaby Lake 7700K for example, which idles much lower and wouldn’t need to overclock.

I'm sure that KL consumes significantly less in practice, especially idle, but for what is worth they are 91W vs 95W TDP.

Anyway, the machine runs an, admittedly overkill, GTX 1070 with a TDP of 150W, so the CPU power usage is the least concern.

Since TDP is not power consumption, the GTX 1070 will most likely consume less power than your CPU because it has much better power saving features.

Also, since CPU's are idle more of the time than under load the savings by using a newer CPU like Kaby Lake or Ryzen could be interesting. There is also the motherboard. Newer boards consume less power because the chips are on a smaller node.

But I guess the money you saved on buying the CPU will outweigh the electricity costs even in countries where electricity is expensive.

Unless he's running 24/7 and paying way too much, yeah, by a large margin. Even these older Xeons weren't that bad at energy saving.

To be honest the machine is turned off most of the time, as I have very little time to play with it.

But the overclock is going to affect actual draw. Not sure by how much... possibly a lot.
