It seems the board might be broken, which isn't great. You might want to consider a bigger ATX motherboard instead.
The board sits between the CPU socket and memory slot. In your photo, the ST (BOOST) label is near the CPU fan connector, which holds the name. Identifying the exact model isn't very useful since the board only has one x16 slot, making it impossible to test different video cards in another slot. Checking the I/O shield ports suggests a DVI port, but this is compatible only with APUs, not CPUs like the 5600X. You mentioned connecting a 4-pin to your 4060 Ti, but video cards typically use a 6-pin connector. The 4-pin is usually Molex, an older standard from AGP or early PCIe cards. Many didn't have a PCIe power connector, so they stuck with the 4-pin. Remove all USB and audio headers, reset the CMOS battery, then try connecting your GPU to verify it powers on.
With the CPU power and motherboard header removed, the behavior remains consistent with the old GPU. The RGB lights will activate fans and the CPU LED will light up during startup. Trying with the new GPU should still work, though there may be no difference in performance.
Have you considered checking the CPU socket or RAM? Occasionally a diagnostic indicator stems from a minor problem.
I need to purchase some thermal paste, but I’m confused about why replacing the GPU would impact either of those aspects.
