Question Ryzen 7950x idle or light load power usage

I am considering buying a 7950x and building a PC on this CPU.
I have seen few posts/sites that people complain about high power consumption of 80-100W in idle or very light load single thread like an open browser.
Can anyone tell me who has such a CPU how it looks in practice, for example playing a video on yt in the browser, what is the power consumption according to hwinfo?
It does not matter if you have overclocked or not, just play some yt video and read hwinfo wattage.

Why are you buying a 7950x to watch youtube with???
Get a little android box that you can connect to the same, or even better a second, monitor and use that.
This is not a post of the type I have doubts about or need advices like that, but there is a specific technical (power) doubt and question. Let's stick to that, and leave the goals to me please. (I have not shared goals in fact)

I have a 7950X - the CPU package runs 55-60 watts at idle or watching YouTube videos. Temp is around 45C.

That said, I have a power monitor on the PSU power plug - at idle/watching videos, total PSU power draw is 180 watts. The CPU is slightly undervolted, the case has 8 fans and AIO pump, 3 HDDs and 6 NVMe SSDs plus the RGB.

This is on an MSI MEG X670E ACE motherboard.

Thanks so good that not 100W at least anyway looks like Raport Lake manages much better
at 5300MHZ, playing yt video nothing else special draw 12-24W (14600K), I know you might say now comparing apples to oranges but not really I saw myself system 14900K and it was around 30W so still 2x less.

It's avg. 2x more power usage @ Idle
as for AMD I guess 2 CCX make this quite high power usage at idle/low usage.

It's not hitting 100w watching YouTube and stuff but it usually spikes to 65w with average of 45w.

A 14900k shouldn't be drawing 30w, if use balanced power profile it should be sitting at below 10w. At complete idle it's sitting at single digits, like 2-3 watts
