Hey Rodney...

New guy to the forums. - Have been watching a lot of stuff on your website for a long time, though!

My question is quite straight forward: Is the high-pitched "whining" from a PSU a bad/potentially dangerous sign for the computer?

I've got a Corsair 750W PSU in my computer, which is giving off a high pitched sound. You have to listen carefully to catch it, but it's there, and quite apparent once you have "caught" it...

Should I consider getting another PSU?

Many thanks

In most cases it's just an acoustic thing and does not mean your PSU will die, however if you are concerned then you should replace it.
