140 ISP2150 2U Rack Server Platform Product Guide
Current Usage
As an overall current usage limitation on the power supply, do not exceed a combined power output
of 167 watts for the +5 and +3.3 volt outputs.
The PCI slots on the server board are rated at a maximum of 5 amperes per slot. The maximum
power allowed for each slot is 20 watts at +5 volts. The average current usage per slot should not
exceed 3.0 amperes per slot; that is, 15 watts.
The cooling efficiency varies per slot; therefore, ensure that adequate cooling is available in the
target slot—especially in an expansion slot drawing more than 2.0 amperes.
Calculating Power Consumption
The total combined wattage for the system configuration must be less than the output of your power
supply. Use the two worksheets in this section to calculate the power used by your server boards.
For current and voltage requirements of add-in boards and peripherals, see your vendor documents.
