PC Only starts up when CPU 4 pin power cable not connected to motherboard

[K3RN3L 54ND3R5]

Title mostly says it all but when i do not have the 4 pin cpu power connector plugged into the motherboard the pc starts up and everything comes on. Once i connect the CPU power connector to the motherboard, the pc will start up and run for about 5-10 seconds and then shuts off again and will keep restarting until i turn off the PSU. Note this is a newly built pc. Thanks in advance for any help/suggestions.

Does the PC detect the CPU in either case? Or are you unable to verify if it does when the 4-pin is actually connected?

Hey i actually fixed it, rookie mistake the RAM slots on the motherboard are quite finnicky for installation and turns out the ram was not in the slot all the way, fixed the issue and the pc is perfect now, thanks for the reply though, appreciate it! Cheers!
