I checked out the cord attachment for my psu that goes into the back of my pc and I realized that it I wiggle it in any direction its loose. The cord is all the way in, cant go in any further but if I move the wire in anyway it just seems loose. I only noticed this when I moved the wire when pc was on and my pc actually lost power. It's never went off for any other reason when I didn't mess with wire. Is this normal? It's the cord that came with my psu.
