Hello! Your new PC isn't turning on properly, and you're hearing a strange buzzing sound from the PSU when it's connected. It seems the smaller connector is causing the issue, but you're unsure why. Since the system won't boot, this could indicate a power or hardware problem. Consider checking the PSU connections, testing with a different power supply, or consulting a technician for further diagnosis.

I realized it was the front panel USB-C that caused the problem. (My Corsair 2500X model) Removing it resolved the issue and let the computer start.
