Z210: Noisy PSU

$

Hello and Good Day!

 

The PSU of my Z210 CMT workstation is noisy, especially when booting Windows 7!

 

The noises are a case of so called "Coil Whine".

 

Some of the noise can be put off by switching "Idle Power Savings" in the BIOS from "Extended" to "Normal".

 

Some other noise cannot be put off by any  BIOS-Menu-Change or Windows-Driver-Update! This persisting noise seems to be caused indirectly by the Intel SSD!

 

The noise is occurring regardless of which OS is installed and used! (tried installing SUSE)

 

Does anyone else owning a Z210 CMT workstation hear coil whine noises from the PSU?

 

Or is my PSU in a bad condition? (purchased a used Z210)
