Output Signal Specifications
Pin 34 at +5 V 1.0 A maximum
Note: The total current output from pin 34 may be limited by the available current from your
computer's power supply. To determine the available current, subtract the maximum
power consumption of the board from the maximum current per slot. The difference, if
less than 1 A, is the maximum current available to pin 34. If the difference is equal to or
greater than 1 A, the maximum current available is restricted by the limitations of the
connector, as shown previously.
