How can I avoid problems with CPU power?
When I attempt to turn on my newly built custom computer, it powers on for 5 seconds then turns off again. The only happens when I have the ATX CPU power cable connected. When this cable is removed and the CPU isn’t powered, the motherboard powers on but doesn’t do anything.
- CPU: Intel Corp i5 7400
- GCard (the same with or without the GPU): Asus NVIDIA GTX 1050 Ti
- RAM: 16 GB (2x8)
- Motherboard: Gigabyte Z390M Gaming
This is not overheating, as the CPU doesn’t even seem to turn on!

You're going to need to start troubleshooting this from the ground up. Remove any non-critical component (all but one stick of RAM, HDD, GPU) and see if it will boot. I would suggested tearing it all apart and working from scratch again, double checking all fits and connections.

Your CPU is not compatible with your motherboard. It is from a previous LGA1151 generation and your new motherboard chipset does not support this CPU.
Your Intel i5-7400 processor is a Kaby Lake processor which is not compatible with the 300 series chipset on your motherboard.
See this chart from the Wikipedia Article on LGA1151 processors:
https://en.wikipedia.org/wiki/LGA_1151
You can also verify this by checking the CPU Support page listed on your motherboard manufacturers website:
https://www.gigabyte.com/Motherboard/Z390-M-GAMING-rev-10#support-cpu
(Unfortunately the table is too large to screenshot, however the minimum currently supported i series CPU is the i3-8100t)

Even with a compatible socket, and the CPU fits, it's still a no-go. Disappointing that cpu's don't follow the cat rule "if it fits, I sits." Interesting, +1

The reason this is happening is that the PCH (Platform Controller Hub) on the motherboard is very tightly coupled to the CPU microarchitecture nowadays. Adjusting the physical characteristics of the CPU every year is unnecessary and would add cost for Intel. So we're left with physically and electrically compatible CPUs that don't work because the PCH is too old. Newer PCHs can generally handle older CPUs, but not always.
