Description
This Mini-ITX board brings AMD's B850 chipset to ultra-compact builds, supporting the latest Ryzen 7000, 8000, and 9000 series processors in the AM5 socket. Despite its 170mm x 170mm footprint, it packs serious connectivity including Wi-Fi 6E wireless, 2.5 Gigabit Ethernet, and comprehensive I/O for high-performance small form factor systems. The B850 chipset positions this as a mainstream option that balances features with value, making it ideal for compact gaming rigs, media centres, or space-conscious workstations.
Memory support extends to 128GB across two DDR5 slots, with ECC and non-ECC compatibility for both consumer and professional applications. Storage connectivity includes two M.2 slots - one PCIe 5.0 and one PCIe 4.0, both supporting 2280 SSDs for fast NVMe storage without cable clutter. The single PCIe 5.0 x16 slot handles modern graphics cards, while 7.1 channel audio processing ensures quality sound output. RGB enthusiasts get two LED headers for lighting customisation.
Setup benefits from AMD's memory profile support for easy DDR5 overclocking, while the included antenna ensures optimal Wi-Fi reception. The box includes mounting screws and other essential hardware for a complete build experience. Power delivery uses a single 8-pin EPS connector alongside dedicated fan and pump headers for thermal management, making this board well-equipped for demanding Mini-ITX builds where every millimetre of space matters.
