Do i have a faulty PSU?

Argh! Every time i even touch the powercable going into the back on my PC into the Hiper 580typeR i hear a crackling noise - is this normal? The slightest movement causes this.

I was just playing NFS-Carbon and the PC just turned off and i think its the PSU or the powercable doing this but i am not sure. Turned on fine again though..

Ok mate i will try another powercable but seeing as this cable is the one that came with the power supply itself i am rather disapointed . When i plug it in it feels as if it is not making good enough contact either!

edit: does it matter if the replacement power cable is generic?
