XBox one s power supply makes noise even though it is completely off?

Hello people have a question about the xbox one s s and when I turn it off completely makes you trz on the power supply in the xbox pretty quiet clacker noises. Thought first it comes from fan but tia comes from the power supply so I'll ask if that is again or I can do something about it lg B.O

Is she right?

akso not: turn off console

but: Settings → General → Turn off console completely

Yes completely switch off in the settings

Boy, boy, what a spelling. Wow!

My dad once told me that this can also be a component in the charger, which is responsible for generating the right voltage. This is the same component that emits a "noise" in some mobile phone chargers.
