Hello, I've brought recently a new PSU Be Quiet Power Supply 1200W ATX 24 pin Straight Power 11 Platinum Active-PFC.
Everything is perfect except one thing that worries a little, when I shut down my pc after a little while a very fade rapid clicking noise like a relay starting to sound, if I turn the PSU off from its switch when the stored power drains completely the sound stops after that I'm turning back on nothing is making noise, only if I turn on my pc and shut it down again after a while the noise starts again.
Is that normal? If yes, what is the purpose of this noise?

Hi, this is the relay for the NTC thermistor, suppressing high inrush currents. It is nothing to worry about.
The inrush current relay only clicks once when the PC turns on, and once when it turns off.
To be clear, you are hearing a rapid, repetitive clicking sound only when the PSU is in standby?
Try enable ErP power setting in your BIOS.
If that doesn't help, I'd suggest contacting be Quiet! I don't believe this ticking is normal for a new power supply.
