PSU making buzzing noise when under load

[XxBahamutGodxX]

Hi there, I recently bought a custom built PC for gaming and it was going fine until my PSU started to make a buzzing noise, it started when I was playing Far Cry Primal on ultra, when it was rendering the environment it started buzzing and as soon as I press the pause menu it stops and begins again when I exit the pause menu.

This also occurs on games like GTA5 with very high settings and Minecraft (with shaders mod), Batman Arkham Knight on ultra. Before it stopped making the noise for the rest of the day yesterday and then today it began again. I'll add that these games are working fine, at 60fps.

I don't think I have warranty for this but it's not a big deal I don't mind spending money for a PSU. Every other post I've seen with this problem is that they haven't really confirmed if the buzzing had actually in the long run affected the PC so I'm not sure if it's worth getting a new one, I don't mind the sound as you can just barely hear it, and clearly hear when your ear is right up to it plus I use a headset so it's fine, it just worries me as I'm not sure if this is normal and if it will damage the PC in anyway. I thought it was because of my games being played at too high of a load at ultra but I turned the graphics down and it still buzzed but more quieter than before.

The games run at about 65 Celsius for the GPU and jumps around from 50-60 Celcius for CPU when under load.

My specs are:
Intel i7 6700k
MSI GTX 1080 Gaming X 8GB
16GB Ram (2 X 8GB DDR4 3200mhz)
CPU cooler is h100i v2 if that matters
And my PSU is a Thermaltake 650w SMART 80 plus bronze

Here is a recording of the sound, sorry it's Dropbox, I'm typing this up on my phone.

Thanks and appreciate any help

Edit: ignore the loud sound in the beginning of the audio

I did not find anything specific to thermaltake but seems the corsair forums have a corsair notice on the matter and looks like good ideas ..

If you believe that your PSU is louder than it should be there are a few things you should check before assuming that the PSU is faulty. First, you should be aware of what can cause the noise that you are hearing. If you are hearing a buzz or electrical type sound, then it’s likely due to a capacitor somewhere in your system that is vibrating at a frequency which is clashing with the rest of the components in the system. Usually this capacitor is either on the PSU, motherboard, or graphics card and you should be able to try a few things to narrow down the issue.

We have seen that the CPU power saving features in the BIOS can cause the PSU to emit the noise. Try disabling these features to see if there is any improvement. ERP, C1E and EIST (Enhanced Intel Speedstep Technology) are few examples of power saving settings, but your motherboard manufacturer should be able to tell you specifically which features your board supports.

We have also seen that some graphics card drivers can contribute to the sound as well. If the problems seem to get worse when loading a 3D application, try booting your system up into safe mode to see if you can still hear the sound. If the sound goes away, then your problem may be software related. We have found that enabling “vsync” in your graphics drivers options can eliminate the sound.

If the previous steps have not eliminated the sound, then you may want to test the PSU in a different system just to be sure that the sound follows the PSU

If the problem persist contact customer service.

Hi mate, thanks for the response, would you have an idea on what is BIOS when he speaks of the CPU. Thanks
