Judging by the video it looks like there's a relay or something flicking inside that power supply at the same time the noise can be heard. Maybe it's one used to switch between 120v and 230v automatically? I can't say for sure, just an educated guess.
now that you mention it, I do see the movement in the video. Good eye, I'll check that out.
