GIGABYTE B650M K DDR5 AMD Motherboard

The GIGABYTE B650M K is a Micro ATX motherboard built around the AMD B650 chipset and the AM5 socket, designed to support AMD Ryzen 7000 Series processors. Measuring 24.4 cm x 24.4 cm, it fits standard Micro ATX chassis while delivering a feature set typically found in larger boards. Memory support is a highlight of this board. Four DDR5 DIMM sockets accommodate up to 128 GB of system memory (32 GB per DIMM) in a dual-channel configuration. Supported speeds run from DDR5 4800 native up to DDR5 6400 via overclocking, with compatibility for both AMD EXPO and Intel XMP memory profiles to unlock rated kit speeds through a single BIOS toggle. The VRM implementation uses an 8+2+1 phase digital power delivery design, providing stable power to the CPU under sustained load. M.2 thermal guards help maintain consistent SSD throughput by managing heat on the two PCIe 4.0 x4 M.2 slots. One slot supports the 2580 form factor and the other supports both 25110 and 2280 drives. An additional four SATA 6 Gb/s ports and RAID 0, 1, and 10 support across both NVMe and SATA devices round out the storage options. Connectivity at the rear I/O includes a USB Type-C port running at USB 3.2 Gen 2 (10 Gb/s), a USB 3.2 Gen 2 Type-A port, two USB 3.2 Gen 1 ports, and four USB 2.0 ports, plus a PS/2 port for legacy peripherals. Networking is handled by a Realtek 2.5GbE LAN chip supporting 2.5 Gbps, 1 Gbps, and 100 Mbps link speeds. Display output for processors with integrated graphics consists of one DisplayPort 1.4 (up to 3840×2160 at 144 Hz) and one HDMI 2.1 port (up to 4096×2160 at 60 Hz). Audio is delivered through a Realtek High Definition Audio CODEC supporting up to 7.1-channel output via three rear audio jacks. GIGABYTE’s Smart Fan 6 system manages the single CPU fan header and two system fan headers, supporting both PWM and DC modes. Each header supports up to 24 W with over-current protection. Fan curves can be configured with up to seven control points in slope or stair mode through the AMI UEFI BIOS interface. The Q-Flash Plus button on the rear I/O panel allows BIOS updates without installing a CPU, memory, or graphics card—useful during initial platform builds. An addressable LED header and an RGB LED header are included for lighting accessories.
