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 t otal wattage for each voltage

level.

3. Add the total wattage for each voltage level to arrive at a tot al combined power

usage on the power supply.
