Load regulation is loose at 12V. It is within 1% at 5V and 3.3V.

I would like to see below 40mV ripple at 12V under full load. The other rails have good enough ripple suppression.

The transformer’s visual impact is remarkable, but it is the optical effect compared to the size of the power supply. Seeing 1200w from such a small 850w power supply always makes a certain sense.
