3.3x25=82.5W 5x30=150W 0.5x12=6W
Note:
The straight sum of the three maximum powers = 238.5W, but considering the 3.3/5V power limit, it may be 170W
+6W = 176W maximum combined power.
+6W = 176W maximum combined power.
5.3.3.12 Voltage
Regulation
The DC/DC converters’ output voltages must stay within the following voltage limits when
operating at steady state and dynamic loading conditions. These limits include the peak-peak
ripple/noise specified. All outputs are measured with reference to the return remote sense signal
(Returns). The 3.3V output is measured at the 3.3 RS point; all other voltages are measured at
the output harness connectors.

Fan-less Operation in Stand-by Mode
The power supply will work indefinitely in standby mode with power on, power supply plus
power distribution board off, and the 5VSB at full load under environmental conditions
(temperature, humidity, altitude) as specified.
