Psu cable missing pin inside socket

[Aspinwallm1]

Hello I am in the process of connecting my XFX TS550 psu to my pc and on inspection of the 24 pin power supply cable that goes into the mobo there was a pin missing inside one of the sockets. This is my first pc build and im unsure wether this is normal or a problem. Any help is much appreciated.

That is where the -5V wire used to run, that was phased out with ATX 2.0 many years ago. If your 24 pin connector had wires going to all 24 pins that would be a cause for concern.
