3 PCIe2 x8 (4) x8 x4

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 ve 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.
