limitation

To determine the maximum allowable
amperage of your option cards and other
equipment, use the table below. It lists the
typical system 5 volt current drain for
your main system board and other
components. Check the 5 volt amperage
rating of the equipment you install and
make sure the total system amperage does
not exceed 30 Amps.
