MSI Z390M Edge AC Schematic
For external connectivity, it also has both analog and digital audio outputs, gigabit Ethernet, WiFi, Bluetooth, four USB 3.0 ports, two 3.1 ports (including one Type C), and even legacy PS/2 ports. Thanks to the Intel graphics on the CPU, there are also HDMI and DisplayPort video outputs available.
I've been planning a new system for my home use (gaming along with some video editing) ever since I heard rumors about the Core i9 9900K and Z390 chipset, and this is the motherboard I have settled on for my new rig. I prefer Micro ATX so that I can have a more compact chassis, without sacrificing too much in the way of expansion space, and this board has the best combination of features and connectivity I have found on a board this size.
