MSI X299M Pro Carbon AC Schematic
For external connectivity it provides two USB 2.0, four USB 3.0, and two USB 3.1 ports - with one of those being a Type C port for the latest peripherals. Digital and analog audio are included too, along with dual Gb Ethernet and 802.11ac WiFi. Internally there are eight SATA 6Gbps ports and two M.2 slot for drives - as well as USB headers for front panel ports / devices. Three PCI-Express 3.0 x16 size slots are present, with two running at x16 speed and one at x8 (or x16, x8, and x4 on CPUs with fewer PCI-E lanes).
Please note that the PCI-Express slot speeds depend on the processor installed. Lower-end chips have fewer PCI-E lanes, so if you plan on using a lot of expansion cards please check with our consultants to make sure you get a CPU that will support everything you need.
