Four DDR4 slots let you start with a modest amount of RAM and add more later without replacing the existing modules. Two M-key M.2 slots take compact SSDs, so you can keep the operating system on one drive and your games, projects or media library on the other, with no extra cables cluttering the case.
The full-size ATX form factor fits a wide range of mid-tower and full-tower cases and leaves comfortable spacing between components. There is no built-in wireless networking, which suits builds connected by cable. If you need wireless, you can add a separate Wi-Fi adapter.
This board suits anyone building or upgrading an AMD Socket AM4 desktop, whether for gaming, home office work or content creation. It also fits users who want a straightforward B550 platform with expandable memory and two drives.
