Description and Specs
A Socket AM5 micro-ATX motherboard designed for AMD Ryzen 9000 series processors. The PRIME B840M-K features an 8+2+1 phase power design with discrete MOSFETs for stable power delivery, alongside comprehensive DDR5 memory support including ASUS Enhanced Memory Profile (AEMP) and AMD EXPO compatibility. Storage connectivity includes dual M.2 slots supporting PCIe 4.0 speeds up to 64 Gbps for rapid boot and application loading.

The board incorporates AI optimisations including AI Cache Boost, which ASUS claims can improve local large language model workflows by up to 29% through CPU cache and memory tuning. Additional features cover AI Advisor software for performance monitoring and thermal management provisions for sustained operation. The compact form factor suits builds with space constraints whilst maintaining core feature support expected of the PRIME series.
