Voltages

The output voltages ranged within the permitted values for the entire duration of the test period. In particular, the important 3.3 V, 5 V and 12 V voltage rails only deviated by a few millivolts from the nominal values. Only under full load were there slightly increased breaks in voltages, which were again well within the specification.
