Strange PSU noise, help please

[Brysger]

Hi, a few days ago I realized a strange noise in my PSU

The first thing I thought was that the noise was coming from the fan, so i pulled out and try to see if I stop the fan the noise will continue, and yes

Today I come to home and turned on the pc, and the noise was different

More like a whistle, and I figured out that the same noise of the PSU, is hearable ( I don't know if this word exist) you can hear the noise right back where de CPU socket is, i mean, the back of the motherboard, I'm trying to send to a technical, but in mi city there's anyone, and I wish to know if take all the PC or only the PSU, sorry for my bad English and thank for the help

It's probably just coil whine, not a problem.

My psu also makes a similar noise, depending on how long you have had the psu and what warranty you got with the psu you might be able to ' rma ' it

Search whatever brand psu you have the put 'rma ' after that, their website should be able to help you.You might be eligible for an exchange or refund
