Worksheet, Total Combined Power Used by the System
1.
From the previous worksheet, enter the total current for each column.
2. Multiply the voltage by the total current to get the total wattage for each voltage
level as indicated in Table A-3.
3. Add the total wattage for each voltage level to arrive at a total combined power
usage on the power supply.
