Power Supply is Squealing

post #1 of 5
Thread Starter 
I have a cooler master 750 watt running on my sig rig and whenever I run a graphics card intensive application it starts making a squealing noise. This just started after upgrading to a gtx 570. Anyone have any ideas of what it could be? As far as I know my system shouldn't be underpowered.

Capacitor squeal, you cannot do anything about it. It happened when you installed your new GPU because when the PSU is under more stress, the capacitors get more stressed, and sometimes they become loose and squeal.

it's normal, and safe, and affects alot of PSUs
if it's annoying you too much, RMA the thing, and ask them to make sure the return unit is ok

Ok good to know, it's not that annoying ( I just drown it out with sound) but I wanna make sure that the thing isn't on the verge of failing. I will replace it soon with a 1k watt but I'm waiting for a good sale. Thanks.

My brother has a cooler master PSU and it does that as well. They seem to be using low quality caps in some of their cheaper models.

^^ i agree, the problem seems to affect lower end units more, but it can affect high end ones too. personally my 650watt is fine
