The Asus Prime X299 Deluxe II is an ATX size, workstation-focused motherboard utilizing the X299 chipset from Intel. That chipset is built to support Intel's Core-X series i7 and i9 processors, along with eight DDR4 memory slots.

A wide range of connectivity is available on this board: six standard USB ports, a pair of Thunderbolt 3 (Type C) ports, 1Gb & 5Gb Ethernet, WiFi6, BT 4.2, and both analog & digital audio outputs. A pair of DisplayPort connectors are present as well, but they are inputs to feed the Thunderbolt ports. Internally there are eight SATA ports, three M.2 connectors, and a mix of PCI-Express 3.0 slots. Some of those PCI-E slots share bandwidth with other connections, as detailed below.

Note the following:
PCIEX1_1 shares bandwidth with USB 3.1 Gen 2 front panel connector(U31G2_E1). It is disabled by default.
PCIEX1_2 shares bandwidth with SATA6G_7.
