Expansion cards
Your computer can accommodate only 6.88-inch PCI expansion cards. If you add an expansion card to
your computer, make sure the component’s power requirements don’t exceed the maximum power
allowances allocated to it by the computer. Power allowances are presented in the following table.
Device Voltage Current Power
PCI expansion cards (15 watts)* +3.3 V 2 A 6.6 W
+5 V 3 A 15 W
–12 V 500 mA 6 W
Communication expansion card
+5 V 500 mA 2.5 W
+12 V 100 mA 1.2 W
* Each PCI expansion card should not consume more than 15 watts of power total.
The communication card should not consume more than 2.5 watts of power total.
