Ripple Measurements
You will see the ripple levels we measured on the rails of the AG-850M in the following table. The limits are, according to the ATX specification, 120 mV (+12V) and 50 mV (5V, 3.3V, and 5VSB).

Ripple suppression might not be up to Super Flower or Seasonic standards, but is still good enough overall.
