Fedora 43 KDE - No display of CPU power consumption - Ryzen Zen3

Hello everyone,

Unfortunately, MangoHud and s-tui do not show me the power consumption of my Ryzen 5900X, Mainboard MSI X570 Unify.

I have read keywords such as “zenmonitor,” “zenpower3,” and “zenergy” online, some of which refer to all kinds of distros, such as Arch. Some of the Gits for the tools are already offline.

What could be the reason for this? Unfortunately, I can’t seem to solve it.


I can see my power consumption via Zenmonitor3, but it is still not displayed on MangoHud.
The CPU temperature is also not visible.

It’s not really a “solution,” but by switching to the CachyOS kernel, I can now see CPU watts/temp. GitHub - CachyOS/copr-linux-cachyos: CachyOS Packages for Fedora
To boot into the kernel, Secure Boot must be disabled in UEFI.

Update: When I disable SecureBoot, I can see the CPU values even with the Fedora kernel.

Does anyone have any tips/ideas as to whether this is due to the kernel, the motherboard/chipset with SecureBoot, or the CPU? Thanks
