Received and installed my new GTX 780 today.
When I go in-game, not even playing yet, my PSU makes some noise.

I attached a recording of the noise it makes. In game it gets worse, but sometimes goes away as well.
Is my power supply not capable of handling the new GPU or is it something else?

(can't attach wave file)

Is the only fix for coil whine a new PSU?

If the PSU can't handle the power it would simply shut off or cause sever instability.
Which Rosewill is it?

It could be a faulty fan bearing.
I took another recording. No way that's just fan noise, it's never made that noise before. It almost sounds like grinding, but the pitch constantly changes. When I'm in game it can go very quiet to louder to virtually gone.
Also verified that it is indeed coming from the PSU.

Here is another one, not sure if it's any better quality.

Could be something touching the fan blades.
Use an ear wig and gently apply pressure with it on the middle of the PSU fan (to slow it down).
Does the noise change with the pressure ?

It does not change. The second I alt+tab out of the game, the noise stops.

Cleaned it out with some air for good measure, no dice.

Hmm. To my understanding, Coil whine is a very high-pitch noise, not grinding.
It's obvious the noise is related to the Current being drawn by the PSU. What was the previous GPU?

It was an XFX HD5850.
The grinding noise does change in pitch, but like I said it's limited to in-game only. It also occured when I fired up and started 3DMark.

When you run 3d mark does it change in pitch after each scene?
Yes, not every single scene, but just about all of them.
It'll change from high pitch to grinding like sound to barely audible and everything in-between.

I had the same issue with a 850w for some reason went through 2 of them so I just went with a 860 is your psu new?
No, it's close to 5 years old. I guess it's time for a new one

Wasn't really planning on getting any other components until my new build.

definitely sounds like coil whine, which is pretty much 100% normal. You may actually be experiencing coil whine twice depending on the PSU. My old Corsair HX850 watt whines like a baby.

It may still be under warranty depending on who you got it form, I would look into cashing that in before it runs out! All you need is the serial number for most companies, though it helps to have the purchase order, it's not always necessary.

Thanks, I'll check that tomorrow.

Yup, guess that's the route I'll go if it's not under warranty.

Thanks for everyone's help, it's greatly appreciated.
