Having trouble finding CPU TDP in AC powered system

I’m running Manjaro on a relatively old PC with an i5 6th gen CPU. I’ve been trying to find out any power readings I can get since I run the PC 24/7.

I have tried the methods posted in
Unix & Linux Stack Exchange and so far I could only get the energy readings through cat /sys/class/powercap/*/energy_uj. Most of the solutions on that link are focused on laptops which provide procfs or sysfs files for installed batteries, and only one answer talked about reading power from ACPI. I tried that solution and installed powerstat from AUR but found this as its output (tail):

This hints that there are no power sensors available!

Any advice would be of great help!
