Expansion card slot identification
This section identifies and describes computer expansion card slots, and presents card configuration
information.
Slot identification and description
The following figure identifies computer expansion card slots.
Figure 5-29 Identifying expansion card slots
The following table describes the computer PCIe card slots.

PCIe2 - x16 75W
3 PCIe - x4(1) 10W
4 PCIe - x16(4) 25W
5 PCI 32b/33MHZ 25W
6 PCI 32b/33MHZ 25W
7 PCI 32b/33MHZ 25W
NOTE: The x1, x4, and x16 designators describe the mechanical length of the slot. The number in
parentheses lists the number of electrical PCIe lanes routed to the expansion slot. For example, x16(4)
means that the expansion slot is mechanically a x16 length connector, with four PCIe lanes connected.
NOTE: Graphics cards greater than 75 watts require the use of an auxiliary power cable adapter.
