Description
The ASUS PRIME B840M-A WIFI brings modern AM5 platform capabilities to a compact micro ATX form factor. Supporting the latest AMD Ryzen 7000, 8000, and 9000 series processors, this motherboard delivers contemporary performance in a space-efficient design that fits smaller cases without sacrificing essential features. The B840 chipset provides a solid foundation for mainstream builds, whether you're assembling a compact workstation or a versatile home PC.
Memory support extends to 192GB across four DDR5 DIMM slots, accommodating both ECC and non-ECC modules for professional applications or standard gaming setups. Storage connectivity is comprehensive with three M.2 slots - two supporting PCIe 4.0 for high-speed NVMe drives and a third PCIe 3.0 slot for additional expansion. The single PCIe x16 slot handles modern graphics cards, while integrated Wi-Fi eliminates the need for separate wireless adapters in compact builds where internal space is limited.
ASUS includes practical installation accessories with screws for M.2 drives and a Wi-Fi antenna to get wireless connectivity working immediately. The micro ATX footprint makes this board suitable for smaller cases while retaining full-size expansion capabilities where they matter most. Four SATA 6Gb/s ports provide traditional storage options alongside the M.2 slots, giving builders flexibility in drive selection and RAID configurations.
