Is passive mode in AX760 really silent?

Hello. I am trying to make a fully passive PC. I have eliminated all noise sources and now the most noisy unit is power Supply - AX760.

Even in passive mode the Corsair is frustratingly noisy - I don't mean it's fan is noisy but sounds that are generated via electronics and transformer.

Is it normal in Power Supply for almost $250? Is there someone who owns the same model? How loud is it?

Yes , it is normal ...when i bought a new psu in 2012 i was thinking on buying a good\long lasting psu so i bought a corsair hx850...it was a disappointment , the noise from the fan ramping up and down the rpm was driving me nuts because at some low rpm the fan generated a noise from the vibration inside the psu chassi\case.

So I decided to upgrade the hx to the ax860 model . Since the first day I notice a electronic" noise just like the old tv's coming from the psu even when was off ...didn't knew if it was a faulty psu or just a feature" XD so I came back to the store and asked if it was possible to try another Ax860 just to check that ... Unfortunately it was a feature so i gave up and decided to go to the big brother , Ax860I

Funny thing is 2 days ago the ax860i died , with almost 6 years of light use ...and now I have to spend more money just to send it to rma
