The noise from the psu is a grinding fan noise and when close a buzzing noise.
The unit is mounted upside down as have a underside vent with filter on Corsair case.

Depending on the age of the unit, could be fan failure or coil whine. Fan failure is easy enough to check for, just spin the fan manually and see if it feels gritty or has resistance to spinning. If it doesn't, it's probably coil whine, which is mostly harmless, just annoying.

The fan sounds like it is going and there is air movement when switched on. So I don’t think it’s anything to worry about. Maybe an upgrade to a more efficient PSU may do.
