Network & Connectivity
Built on the AMD A320 chipset, the ASUS PRIME A320I-K AM4 Mini-ITX Motherboard supports first-, second-, and third-generation AMD Ryzen processors with an AM4 socket. The two 288-pin DIMM slots support up to 32GB of 3600 MHz DDR4 RAM. There is a single PCIe 3.0 x16 slot. There are also four SATA III 6 Gb/s connectors as well as one M.2 socket. Other notable features are Realtek RTL8111H Gigabit Ethernet LAN, Realtek ALC887 eight-channel HD audio, and an ASUS Aura Sync header, which is an onboard connector for RGB LED strips (sold separately).
This motherboard has an onboard connector for ASUS Aura Sync RGB lighting support, so you can sync additional LED strips and other compatible hardware devices.
The AMD A320 chipset supports AMD AM4-socket Ryzen processors, 7th Generation A-series APUs, and Athlon CPUs. It provides two USB 3.2 Gen 1 ports, and four SATA III 6 Gb/s ports for faster data retrieval.

Whether you build a new PC or upgrade the existing one, the motherboard is the most vital component to choose when you have already picked the processor of your choice.
It is important to keep a few things in mind while purchasing the mainboard:
You can single out a great CPU from either Intel or AMD, but whatever CPU you choose, make sure your mainboard has the right socket for the selected CPU. The latest mainstream AMD chips use AM4 sockets while current Intel 9th Gen Core CPUs require LGA 1151v2 sockets.
Motherboards typically come in three sizes from largest to smallest: ATX, Micro-ATX, and Mini-ATX motherboards. ATX motherboards offer the highest number of RAM and expansion slots. If you are looking for a budget build, you can use a smaller chassis with the micro or mini boards, but you'll have to settle for fewer PCIe slots, RAM banks, and other connectors.
Most mainstream boards these days have four RAM slots, although Mini-ITX models often have just two, and high-end boards frequently offer eight. The amount of slots, of course, limits the amount of RAM you can install.
It’s essential to check the I/O area on a motherboard to make sure it has the external connection options you need. You may need more USB 3 ports while others may want more audio ports. Among the most common ports, there are USB 3, USB 2, audio, USB type C, USB 3.1 Gen1 and Gen2, HDMI, Display port, PS/2 and Thunderbolt 3 ports. Ports one probably want the most are USB 2 and USB 3 Gen1 ports, as the first one is perfect for keyboard, mouse, and many other devices and the later one work with most peripherals. USB 3.1 Gen2 and USB Type-C ports will come handy in the near future, although most peripherals do not support this standard yet.
