PSU making electrical buzz

Recommended Posts

Posted · Original PosterOP

Hello, 

 

my psu CX 750M makes electrical buzz. System randomly  freezes for a second when the buzz stops for a second, and then runs as usual. 

Hope someone would be kind enough to solve this.

Are you sure it isn't coil whine?

Sounds like Coilwhine.

 

Not a lot you can do. And the CXM (2015) is known to be a PSU prone to whining

@GoldenLag PSUs coils are held on by this adhesive to prevent coil whine, sometimes this adhesive or glue substance melts off over a period of time and can make the coils vibrate more thus inducing coil whine.


OP, if your willing to open your PSU, you could check if this is the case and reapply the adhesive or glue substance.
