High pitch noise

[Pantalaimon]

I recently built a new system of a Seasonic 660W PSU, R9 280x, 4670k, 8GB RAM.

I noticed that when I open certain games I can hear a (fairly quiet) high pitch whining sound. I'm not entirely sure where it's coming from, but I'm guessing it might be coil whine from the power supply?

Any thoughts?

More than likely GPU, turn vsync on in the drivers and I bet it dissapears

Is it a seasonic platinum 660w?, I recently had to RMA one for similar constant whining.

Yeah it is. I expect more for the price you pay for that thing.....

I had the same problem with my 650w M1211 psu go in your bios and check that the c power states are enabled thats what the seasonic guy I spoke to told me to do and it worked like a charm.

I think that they have revised the unit, looking at my replacement PSU the side of the box says the model is SS-660XP²

I haven't tried it yet though.

Whilst I can't help with the resolution of the issue, this high-pitch noise is known as 'capacitor whine' and can be the result of less-than-stellar quality components.

I've seen some really weird fixes in the past such as (and don't do or quote me on this), putting nail polish over the offending capacitor!
