Anandtech peaked M1 Max power at 43w, but that still included some GPU and other SoC usage. Doubling that gives 86w as an absolute max.

Anandtech peaked out the 5950 actual power consumption at 142w.

Anandtech peaked out the 12900k at 259w of actual power consumption.

AMD lists TDP for 5995WX at 280w. The 3990X has an identical TDP and it's actual power consumption would go up over 300w IIRC.
