Builded brand new PC yesterday and immeadly noticed that its making high pitched "cricket/chirping" sound. I't seems to be coming from the PSU (brand new Corsair RM750x)

Sound is barely noticable while PC is idling but as soon as I put some heavier load the sound starts. Not sure if it's safe though.

Specs:

Intel I7 7700k (stock speeds)
Asus Maximus IX Hero Z270
16Gb Kingston FuryX 2666Mhz DDR4
MSI GTX 1080 Gaming X 8G
Corsair RM750x


Sound file : https://ufile.io/gu5vw

Any thoughts?

EDIT: RMA'd the Corsair psu and threw good old CM 650GX PSU inside the PC, noise is gone now.

Sounds like the fan,unless you wanna risk undoing the case and removing the fan and fixing and replacing it ,I would ,But I have lots of 200 mm fans ,I always remove them from dead power supplies for that reason.But unless your'e totally confident ,In doing this and can be sure the noise is coming from the fan,I recommended not doing it.You have to do an RMA .If you don't know what that it is google it ,Its a method of warranty return using post and you will get a new one .
