So today i built a PC , When the computer is powered on normally without any USB connected the computer turns on and works , but when u turn the system completely off (from the psu and pull the cable out) and then connect a USB device from the rear and the turn the PSU switch on the House breaker will trip , but once u turn the switch off , turn the trip back on and then turn the PSU switch on without removing the attached USB then it will turn on normally , this doesnt happen consistently but happens from time to when a New USB is introduced while the power is cut off and the PSU is turned off and then power is given back from the PSU.
What could be the issue?
