    I know that Delta power supplies make a click sound when electricity cable is connected. My old Mac Pro 2008 does that, the new one doesn't. Does it mean I got AcBel power supply ?

    My 2010 clicks when switched on. Why is it an issue?

    Mine too, but what about if you plug cable to it and do not power it on ? Is there any sound then ?
