My new power supply emits loud whining noise.

This is a S-1000-36, 27A supply. Is this normal? My 24V PSU is not so loud.

Sounds like a fan, maybe you could replace the fan with a better one, Generally, i’ve found its worth it to pay up and get a meanwell supply.

Agree:) My 24V PSU is a Meanwell.
