Cooler Master iGreen PSU strange noise

[jovovick 0]

Dear all,

i recently purchase a iGreen 500w psu, the psu is emitting a "bizzzz" noise once in a while.

The noise occured randomly whether the psu is on load or not.

i was wondering to return the psu or is that normal ?

i read a lot from other members' post and from other forums, some said to return if it got noise, some said is normal.

What should i do ?

regards,

jovovick

You sure it doesn't depend on load?

Coil whine mostly depends on that so if not it might be something hitting lightly to fan blades.

hi EsaT,

i am running nvidia 8800, when playing games the buzzing noise is not present all the time, it really occurred randomly.
