MSI MAG B550M MORTAR WIFI Schematic
For external connectivity, it also has both analog and digital audio outputs, 2.5Gb Ethernet, WiFi 6, Bluetooth, six USB ports of varying speeds (including one Type C), and even a legacy PS/2 port.
A couple of oddities about this board are worth noting, but shouldn't impact most users:
- The HDMI and DisplayPort connections on this motherboard are for CPUs with built-in graphics, but the higher-end Ryzen chips we carry don't support that feature (since almost everyone uses a dedicated video card)
- If a second M.2 drive is installed, it will disable the bottom PCI-Express x4 slot
- The onboard NIC does not support Linux, so users of that OS will want to have a dedicated network card added
Note: This board has one Gen4 M.2 slot and one Gen3 M.2 slot for NVMe SSDs. Putting a Gen4 M.2 drive in the Gen3 slot will result in Gen3 speed. Also, populating both M.2 slots will disable the bottom PCIe slot. Please talk to a consultant if you have additional questions.
