Ticking Noise from power supply even when iMac is not switched on?
My 27” iMac Mid 2011 power supply makes a constant electrical clicking/ticking noise when the machine is on standby ie. power cable in, but imac not powered on.
I have replaced the PSU with another pre-owned one, which basically does the same thing. Is this normal or have I got two dodgy power supply’s?
When you say the machine is on standby, do mean it is asleep?

Sorry, No I mean when the iMac is shut down and the power cord is connected and the plug socket is switched on.

I have the same problem. The imac does not always turn on. I also have the ticking sound (very soft). With the imac turned off and the powercord attached, it makes an ticking sound (PSU area).
