When I plug the power cable from the plug to the PC into my PC, it seems like it only goes about halfway in, and makes a quiet high pitched noise whenever it's plugged in, however I'm able to use the PC perfectly fine but I'm worried, and it's also a problem because the slightest movement can cause my computer to lose power because of the very...wiggly power lead. Any help would be appreciated. Thank you.

I should also mention my PSU is a 450W Corsair. I'm not sure the exact model.
There's probably something stuck in there.
I've just checked and I can confirm that there is nothing stuck in the plug nor the socket.
