Corsair HX750i squeak, what could be the reason?

Question

Power Supply

Good afternoon.
I recently updated my power supply for a Corsair HX750i. He has a reserve of power. I heard a squeak when I bent down near the power supply so that my ear was close, when I sit near it (the computer is on the table), I don’t hear the squeak. I also noticed that if you turn off the computer (do not pull it out of the socket, but only the system itself), then the squeak remains. In order not to distract people, I decided to google this question on my own, especially since I had already encountered singing chokes on the vidyuhi.
Unfortunately, the information turned out to be very ambiguous. Someone writes that there is nothing wrong with that, singing capacitors, resonance, school-level physics, everything is fine. But they also wrote that the problem could be in the standby power capacitor and so that the unit does not explode, it generally needs to be turned off every time from the outlet.
In the end, it is only clear that nothing is clear. I hope for your help, otherwise I do not understand whether it is worth worrying about this or not.
PS. I ran tests in Aida and looked at the voltage, there are no drawdowns. Under load, the squeak does not increase.
Thank you for attention.

My opinion is that you should not worry, it is the inductors (chokes) that vibrate. The power supply can explode only in one case - the neighbors will burn out the phase, 380 V will come to the outlet and the capacitors will bang. In other cases, as a maximum - smoke, fire, but not an explosion. And certainly a squeak does not indicate a possible threat.
