3.7 OUTPUT OVERSHOOT/UNDERSHOOT
No output voltage shall overshoot / undershoot or generate spikes at
turn-on or turn-off, during momentary power loss, output short, or realistic
input voltage or output load changes, Overshoot/undershoot is defined as
any output that exceeds the voltage tolerance plus or minus an additional 5%.
All outputs shall be measured with minimum load (COND.3)
Overshoot Undershoot
+3.3V 3.63V 2.97V
+5V 5.5V 4.5V
+12V 13.2V 10.8V
-12V -13.8V -10.2V
+5VSB 5.5V 4.5V
3.8 EFFICIENCY requirement of main output
The PSU should be a minimum of 87% efficiency under 100% of full load and
minimum of 90% efficiency under 50% of full load, and minimum of 87%
efficiency under 20% of full load.That should be tested at nominal Input
voltage is 115V/60Hz and load conditions defined in below Table.

(230Vac input/ minimum of 90% efficiency under 50% of full load)
3.9 EFFICIENCY requirement of standby output(230V/50Hz)
The +5Vsb supply efficiency should be greater then 50% with a minimun
loading of 100mA and input voltage is set up at 230Vac/50HZ when main O/P
off ( PS_ON# high state).
