I've been having some issues with my motherboard and I think I've tracked it down to a voltage problem. About a month back when I moved into my new case, the clip that holds the 20+4 pin inplace on the motherboard broke. I've tightened it up and the problems seem to go away. The problem is, it will come loose again. I'm going to change a lot of parts soon so I can't superglue it inplace, but the PSU is not one of those parts that I have a budget to replace. The PSU itself is fine, it's a 480W from Rosewell that I got at newegg.

Does anyone have any suggestions on how to secure it?
