Connectors and I/O

In total, MSI equipped the X299 Gaming Pro Carbon AC motherboard with eight SATA 6Gbps connectors, which have all been natively wired to the PCH. Below the first PCIe x16 slot there is the first M.2 slot and on top of the fourth full size PCIe slot, there is the second M.2 x4 Gen 3 slot. With this motherboard you get four PCIe x16 Gen 3.0 and two PCIe x1 Gen 3.0 slots and all of the PCIe x16 slots received metal reinforcements framing them. From top to bottom the full-sized PCIe slots have been wired using 16 lanes, 4 lanes, 16 lanes and 8 lanes. With a 44-lane CPU, you can run 16x/16x SLI/CrossFire and 16x/16x/8x CrossFireX (3-way). Basically these are the standard options you get with any Intel X299-based motherboard, that does not feature a PLX chip. The placement of the PCIe connectors has been well thought. Furthermore we also see all the bells and whistles you'd ask for in the event of overclocking.



The MSI X299 Gaming Pro Carbon AC motherboard features a total of six fan headers, which is enough to provide a normal gaming rig with enough of fresh air. A closer look at the pictures below shows where they have been placed. All six fan headers feature 4-pin and support PWM functionality. Therefore it's possible to control fan speeds from within Windows as well as the BIOS.



Looking at the external connectors placed directly at the I/O-panel, MSI equipped the new X299 Gaming Pro Carbon AC motherboard with a P/S2 connector, four USB 3.1 Gen1 Type-A ports, one USB 3.1 Gen2 Type-A port, one USB 3.1 Gen2 Type-C port and three USB 2.0 Type-A ports. Furthermore there is one Gigabit Ethernet port and the analogue audio panel with optical out as well as a WiFi module with two connectors for antennas.
