Worksheet, Total Combined Power Used by the Server
3. From the previous worksheet, enter the total current for each column.
4. Multiply the voltage by the total current to get the total wattage for each voltage
level.
Add the total wattage for each voltage level to arrive at the total combined power usage
for the power subsystem.
Caution: Do not exceed a combined power output of 170 Watts for the +5 V and +3.3 V outputs.
Exceeding a combined 170 Watts will overload the power subsystem and may cause the
power supplies to overheat and malfunction.
