weird psu noise

Hi Hope you all are doing good actually my psu is making somewhat of strange noise I can't determine what the cause and why it's happening ....it's certainly not coil whine or fan noise as psu fan requires at least of 40% load to start ........ I am attaching a video of the psu here kindly help...
