Load regulation is loose at 12V, the most important rail, and tight enough on the minor rails.

A glance at the light loads table is always useful, as the PSU will typically operate at light loads.

I would like to know the noise output of the electric circuit in the PSU. My SF1000 outputs a 14953hz noise, it gives me headache. I would like to get something that don’t have this noise.
On 220V
this is not possible because each PSU once connected to a specific system affects it, so frequency analysis on a single PSU alone won’t mean anything regarding coil whine.
