Load regulation is within 1% at 12V, but loose on the rest of the rails.

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

Ripple suppression should be better at 12V. It is not good at 5V either.

Any update for FSP VITA GD, i’ve seen recently had cybenetics logo on box, hope you will review soon because it was the best selling budget psu on my country 😃
once I find the time yes I will review that, too.
