Small ticking sound from psu when turning comp on.

Is it normal? I have a Seasonic X 1050. When I turn my computer on, the psu makes a small tick/click sound, not loud, but loud enough to make me wonder what it is. Can anyone tell me what it might be?

Thanks for answering!

    It is hard to say without knowing the construction of the PSU. In some units, a large inductor is being energized at switch on, and de-energized at switch-off, and this sometimes makes a tick sound, almost like a relay being engaged.

    But usually it is nothing to worry about.
