Newly built pc turns off after 20 seconds

[zachary.ceulemans]

Hi all,

I made a build with the following parts: link.

The pc starts up, fans turn on for both the case and the cpu, but it turns itself off after 30s and restarts. Followed some troubleshooting tips and kept removing parts and retesting. I'm down now to just the MOBO, CPU (+ cooler), RAM and PSU, but the error just keeps happening. I should mention there's no beeps or BIOS.

I also noticed there's no light on the MOBO, just on the CPU fan. Could that have something to do with it?

Can provide pictures if needed.

Hi, The link does not work.

1) does your mobo have a separate power connector for the CPU, this is usually 4 pin or 6 pin and if so, do you have this connected. Not having this connected causes such an issue.
2) I recently had the same problem, although mine would only power on for a couple of seconds. The issue turned out to be the PSU was faulty.
