9.2.1 Output Power / Currents

The following table defines power and current ratings for this 400W power supplies. The
combined output power of all outputs shall not exceed the rated output power. The power
supply must meet both static and dynamic voltage regulation requirements for the minimum
loading conditions.
Voltage
+3.3 V
+5 V
+12 V1
+12 V2
-12 V
+5 VSB
Notes:
1. Maximum continuous total DC output power should not exceed 400W.
2. Peak total DC output power should not exceed 450W.
3. Peak power and current loading shall be supported for a minimum of 12 seconds.
4. Combined 3.3V and 5V power shall not exceed 80W.

9.2.2 Power on loading

The power supply shall operate at lighter load conditions when the system first powers on.
Under these conditions the voltage regulation limits are relaxed. The following
power on loading and voltage regulation requirements. Time duration is 1 second during power
on.
Voltage
+3.3 V
+5 V
+12 V1
+12 V2
-12 V
+5 VSB

9.2.3 Grounding

The ground of the pins of the power supply output connector provides the power return path.
The output connector ground pins shall be connected to safety ground (power supply enclosure).
The power supply shall be provided with a reliable protective earth ground. All secondary
circuits shall be connected to protective earth ground. Resistance of the ground returns to
chassis shall not exceed 1.0 m. This path may be used to carry DC current.
