ASUS PRIME B650M-K AMD AM5 Micro ATX Motherboard

The ASUS PRIME B650M-K delivers robust performance for AMD Ryzen 7000 Series Desktop Processors in a compact Micro ATX form factor. Engineered with DDR5 memory support, PCIe 5.0 connectivity, and comprehensive cooling solutions, this AMD B650 motherboard provides the foundation for high-performance PC builds.

AMD AM5 Socket and DDR5 Memory

Built for AMD Ryzen 7000 Series processors, the PRIME B650M-K features the AM5 socket with dual-channel DDR5 memory support up to 96GB across 2 DIMM slots. Memory speeds reach up to 8000MHz (OC) with AMD EXPO profile support. ASUS OptiMem II technology optimizes trace routing and ground layers to preserve signal integrity for improved memory overclocking performance.

PCIe 5.0 Storage and Connectivity

The motherboard includes two M.2 slots: one PCIe 5.0 x4 slot (PCIe 4.0 x4 with Ryzen 8000 Series) and one PCIe 4.0 x4 slot, both supporting 2242/2260/2280 form factors. Four SATA III ports provide additional storage options. Expansion capabilities include one PCIe 4.0 x16 slot and two PCIe 4.0 x1 slots.

Comprehensive Cooling Design

The PRIME B650M-K features VRM heatsinks, M.2 heatsink, and PCH heatsink to maintain optimal temperatures. Three hybrid fan headers (one 4-pin CPU fan, two 4-pin chassis fans) work with Fan Xpert 2+ software for intelligent thermal management under demanding workloads.

Ultrafast Network and USB Connectivity

Realtek 2.5Gb Ethernet delivers high-speed wired networking. Rear I/O includes two USB 3.2 Gen 2 Type-A ports, two USB 3.2 Gen 1 Type-A ports, and four USB 2.0 ports. Front panel connectivity supports one USB 3.2 Gen 1 Type-C header, two USB 3.2 Gen 1 headers, and four USB 2.0 headers.

Display and Audio Features

Integrated graphics support includes one HDMI port and one VGA port for flexible display configurations. Realtek 7.1 Surround Sound High Definition Audio CODEC with three rear audio jacks delivers quality audio output.

Aura Sync RGB Lighting

Customize your build with onboard Addressable Gen 2 RGB headers (2x) and one Aura RGB header. Easily sync RGB LED strips with Aura Sync-compatible hardware for coordinated lighting effects.

BIOS FlashBack and Tuning

BIOS FlashBack button enables easy BIOS updates without CPU or memory installation. Intuitive software and firmware provide performance optimization controls for system tuning.
