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.
