Four DDR4 slots let you start with a modest amount of RAM and add more later as your workload grows. The two M.2 slots let you fit a pair of compact SSDs for the operating system, applications and games. This keeps the case tidy and cuts down on cabling compared with traditional drives.
The AM4 socket and B550 chipset make this board easy to pair with existing AMD hardware. The ATX layout fits standard PC cases. There is no built-in Wi-Fi, so it suits setups with a wired network connection or a separate wireless adapter.
This board is a sensible pick for home and office PCs, budget gaming builds and upgrades of older AMD systems where you want to reuse DDR4 memory.
