So recently i have been having a start up issue on my iMac. It boots up but when the chime is made it shuts off and is only able to be rebooted after main power is disconnected only to do the same thing once re booted again. I’ve done some digging and I am noticing that when the display is disconnected from the power supply it boots up and chime sounds full and I can hear fans and harddrive working. Is this a symptom of a failing power supply.
