ASUS PRIME B650M-K mATX Motherboard | AM5 | 2x DDR5 Slots
Description
The ASUS PRIME B650M-K brings AMD's B650 chipset to a compact mATX form factor, making it an ideal choice for smaller builds that still need modern platform features. This motherboard supports AMD's Ryzen 7000 series processors through the AM5 socket, delivering the performance foundation for both productivity work and gaming in a space-conscious design. The B650 chipset positions this board as a mainstream option that balances essential features with affordability, perfect for builders who want current-generation hardware without paying for premium extras they won't use.
Memory support extends to DDR5 with speeds up to 6400MHz across two DIMM slots, accommodating up to 96GB total capacity. The board includes two PCIe 4.0 x16 slots for graphics cards or expansion cards, plus two additional PCIe 4.0 x1 slots for further connectivity options. Networking comes via integrated 2.5Gb Ethernet, while display outputs include both HDMI and VGA for flexible monitor setups. Storage connectivity features PCIe 5.0 M.2 support for the fastest NVMe drives, and USB options span from rear USB 3.2 Gen 2 ports to a front-panel USB 3.2 Gen 1 Type-C header.
Setup benefits include BIOS FlashBack for easy BIOS updates without a CPU installed, plus support for both ECC and standard memory modules. The board supports AMD's EXPO memory profiles for simple one-click memory overclocking to rated speeds. Aura Sync RGB compatibility lets you coordinate lighting effects across compatible components, while the included I/O shield, SATA cables, and user documentation get your build started immediately. The RGB LED pin header provides additional lighting control options for case modifications or RGB strips.
