So recently, i swapped cases to a NZXT S340. after i was done i put the power cable in and noticed cracking. the cracking noise was familiar before i switched cases and that was when the cracking was coming from the actual cable because it wasn't connected properly. the power cable went in smoke for bit NOT the power supply, so now my power cable is a little beat up but it still worked. but after this case switch it doesn't look like its coming from my power cable anymore 🙁
