The ASUS Prime B550M-K is a Micro-ATX motherboard for AMD AM4 processors, built on the AMD B550 chipset and designed for Ryzen builders who want reliable performance in a compact form factor. It supports DDR4 memory across four slots, giving you room to grow your RAM configuration over time.

Flexible Expansion Without the Bulk

• AMD AM4 socket with B550 chipset — compatible with 3rd Gen AMD Ryzen processors
• 4x DDR4 memory slots for dual-channel configurations and future upgrades
• 2x M.2 slots plus a PCIe 4.0 x16 slot for fast storage and discrete GPU support
• 6x USB 3.2 ports alongside PS/2, RJ-45, and three audio jacks on the rear I/O
• Multiple display outputs — D-Sub, DVI, and HDMI — for integrated graphics connectivity

This motherboard suits budget-conscious PC builders, home office system upgrades, and compact desktop builds where an AM4 platform with solid expansion options matters more than high-end overclocking headroom.
