2.2.3 EFFICIENCY

1) The power supply at full load provide DC conversion efficiency 68% minimum.

(EX = +5V:15.0A +3.3V:10.0A +12V:5.0A -12V:0.2A +5VSB:2.0A)

2.2.4 OUTPUT RIPPLE/NOISE

. The measurements should be made by crossing a 10㎌ electrolytic capacitor and

a 0.1㎌ Ceramic capacitors at each output with measuring band width from DC to

20MHz.
