PSU whine

[G-Sharp]

Hello guys

I recently got a computer put together (see sig) but I'm having a problem with my AX850 PSU. It's making a very noticeable screeching sound when my GPU is under load. For instance, when I'm running cinebench, the PSU makes a different pitched whining sounds every time the scene changes in the car chase video. It seems to be synchronized with the amount of load the GPU dishes out.

Is this a common problem, and if I RMA the PSU, what are the chances that a new one will come without the whine?

It's really annoying, especially when the rest of my computer is pretty much silent.

OP - Are you sure it's the PSU? Capacitor whine is common from graphics card that's all. And as it does only happen when your GPU is at a certain load...

Out of interest does it occur while on 2D loading screens or just actually in game and playing?

The noise is definitely coming from the PSU. There is also a very feint (i have to put my ear right up to it to hear it) whine when idle. And no, it doesn't whine on load screens, only in game.

I've sent an email to get it exchanged, so we'll see what happens.
