110% Load 46.3 mV 20.4 mV 19.6 mV 17.9 mV Pass
Crossload 1 15.0 mV 14.2 mV 16.2 mV 7.2 mV Pass
Crossload 2 11.4 mV 15.1 mV 8.5 mV 7.4 mV Pass
Crossload 3 10.3 mV 9.1 mV 18.0 mV 6.1 mV Pass
Crossload 4 40.1 mV 16.4 mV 11.7 mV 12.3 mV Pass

Ripple suppression doesn’t stand out, but it is decent, given the PSU’s budget platform.
