Install ThrottleStop and see if you can fiddle with C-States/EIST or whatever they call it these days. Some sort of CPU power saving options. Those settings may be in the BIOS as well.
I remember that with my other CPU (which was a 3rd gen, ivy bridge, so maybe not that relevant) if I disabled all the power saving options the idle power would be like 50W.

Also, I notice that on Win7 the CPU voltage is much higher, which also points to a power saving option not being set when it should. If the BIOS settings don't help, give Throttlestop a try, it really works for tuning your CPU power consumption.

ThrottleStop really makes a difference! The CPU power reduce to 10W that's acceptable for me.

I enabled C1E.

 

Thank you very much for the solution.

Hello guys,

I've managed to install Windows 7 SP1 on Asus mainboard with B660 chipset. CPU is i7-12700F.

It works fine but one issue with power consumptions. The CPU power reported by Aida64 software is constantly above 30W, even when there is no load on the system.

I install windows 8.1 & not having that issue.

I also check power consumption with external device and same result, 90W compare to 60W on Windows 8. CPU temperature is also higher.

Any idea on how to solve this problem. I really want to run Windows 7.

Thank you!
