Socket AM5 DDR5 Platform

The GIGABYTE B650M K is a micro-ATX motherboard built for AMD Ryzen 7000 series processors. It uses the AMD B650 chipset and provides four 288-pin DDR5 slots supporting up to 128 GB of memory at speeds of 5200, 4800 or 4400 MT/s. A direct 8+2+1 phase digital VRM and M.2 thermal guards help maintain stable operation.

Ideal for Compact Builds

This board suits builders who want a capable AM5 foundation in a smaller chassis with dual M.2 storage and 2.5 GbE networking. It is less suited for users needing multiple PCIe x16 slots, extensive rear I/O or built-in Wi-Fi, as it offers only one full-length PCIe 4.0 x16 slot and a single PCIe 3.0 x1 slot.

Capacity and Headroom

Dual-channel DDR5 up to 128 GB gives ample headroom for gaming and content creation workloads. Two PCIe 4.0 x4 M.2 connectors and four SATA 6 Gb/s ports support RAID 0, 1 and 10 for both NVMe and SATA drives. The single x16 slot limits multi-GPU setups, and the lone x1 slot restricts additional expansion cards.

Highlights

  • Supports Ryzen 7000 Series CPUs via AM5 socket
  • DDR5 memory up to 128 GB with AMD EXPO and XMP profiles
  • 8+2+1 phase digital VRM for stable power delivery
  • Two PCIe 4.0 M.2 slots plus USB 3.2 Gen 2 Type-C connectivity
  • 5 GbE LAN for fast wired networking

Questions about this item

Do I need DDR5 memory modules for the four 288-pin slots?

Yes, the board only accepts DDR5 DIMMs at 5200, 4800 or 4400 speeds, up to 128 GB total in dual-channel mode.

Can I keep my PCIe 3.0 add-in card in the x1 slot?

The x1 slot runs at PCIe 3.0 x1, so a PCIe 3.0 card will work at its rated speed.

How do I confirm the 2.5 GbE LAN is active after build?

Check the adapter speed in the OS network settings; it should report 2.5 Gbps when connected to a 2.5 GbE switch or router.
