PSU click noise at shutoff - normal?

Dogway · 2 Jan 2014 at 12:20

Hello, I just built a silent PC with a Dark Power Pro 10 PSU, being the crown jewel of beQuiet! I thought it was a safe bet, but whenever I turn off the PC I get an unpleasant and irritating/unsteady click noise. beQuiet! says it's normal because the "inrush current/power limiter relay", but I want to know if this is also the standard in other brands, a google search brings nothing about this.

Thank you!

single click noise, sometimes also at startup, but fainter

OK, so harmless but not usual.

I wonder if the click is on my model, or unit only.

Well, probably isn't as loud as mine.
Here I have the PSU at only 50cm from my ear, because the case is on desk, and PSU on the front side. It is indeed a switch like sound. I bought beQuiet because they said to have dealed with the electric noise (or was it coil whine?). Maybe I've been tricked : /

edit: well, probably I'm not going to go through the hassle of a refund only for that...

I know... I just want to know how to look things at.
Is it by design? or is it just my unit? I guess the latter but maybe someone with another Dark Power has to tell.
