Question on how to set a watts limit for alderlake cpus?

[xxMrTimelessxx]

I want to know how to set an upper limit for the intel 12900k when it comes to the most watts it can draw. I still want the chip of course to manage itself on how much voltage etc is needed to be stable I just want it to know it can’t go higher then this amount of watts. Only way I know how to do it is by undervolting and setting a static voltage to lower power draw/wattage but I don’t want to do that as that’s not the most efficient way since the cpu can’t manage itself to run lower then needed and raise power to the max watts I allow. Hope this makes sense any help would be nice

High end motherboards typically let you set the power limits in the BIOS.

PL1 is the long term turbo power limit and PL2 is the short term limit. If you never want to see more than 200W, set PL2 to 200W.

 

You can use ThrottleStop 9.4.6 and probably Intel XTU to adjust these limits in real time. When you find some values that work well, enter them into the BIOS.
