Table 3-5	PCI slots
Slot	Type	Mechanical compatibility	Electrical compatibility
1	PCIe2 x4 (1)	x4	x1
2	PCIe3 - x16	x16	x16
3	PCIe2 - x8 (4)	x8	x4
4	PCIe3 x8	x8	x8
5	PCIe3 x16	x16	x16
6	PCI 32/33	PCI	PCI

NOTE: The PCIe designators indicate the mechanical connector size and number of electrical PCIe lanes routed to an expansion slot. For example, x16 (8) means that the expansion slot is mechanically a x16 length connector, with 8 PCIe lanes supported.

Slot two is the primary graphics slot; slot five is the secondary graphics slot.

Slots one, three, and four use open-ended PCIe connectors, so a PCIe x16 card can be inserted. Graphics cards greater than 75 watts require the use of an auxiliary power cable adapter.
