Bong noise when system shuts down or turns on from PSU.Corsair 750 RM

I have a Corsair RM 750 that makes a single click sound (like a switch going off) after the computer turns off or turning ON or going to sleep mode. Anyone else with the psu that experience this? Is this common to Corsair 750 RM or i should get another one? It sounds like a loud bang.



Here is the video with similiar noise but on model HX Corsair :

That noise you are hearing is the PSU powerup/shutdown relay clicking, it's not unusual to hear it, some are louder than others it's all down to how well the relay was lubricated when manufactured, it's not detrimental to it's operation.
