Product Code:PRIME-B840M-A-WIFI-CSM
Features:
ASUS Prime series motherboards are expertly engineered to unleash the full potential of AMD Ryzen 9000 series processors. The PRIME B840-PLUS WIFI-CSM motherboard provides users and PC DIY builders with a range of performance optimizations via intuitive software and firmware features. It’s designed to be Advanced AI PC-ready, offering the power and connectivity needed for demanding AI applications.
Digital Power Design
PRIME B840-PLUS WIFI-CSM features an 8+2+1 phase power design with discrete MOSFETs, ensuring efficient and stable power delivery for AMD processors plus steady performance for day-to-day use.
Enhanced DDR5 performance
Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B840-PLUS WIFI-CSM maximizes the potential of your DDR5 modules, from entry-level to extreme-speed kits.
For entry-level modules without EXPO support, ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimized profiles for enhanced performance.
For those looking to surpass stock DDR5 speeds, the PRIME B840-PLUS WIFI-CSM offers extensive AMD Extended Profiles for Overclocking (EXPO) support and a wide array of UEFI settings for further performance tweaks.
Three M.2 slots (up to 64 Gbps)
PRIME B840-PLUS WIFI-CSM offers a total of three M.2 slots, including two that support data-transfer speeds of up to 64 Gbps via PCIe 4.0, and one that supports PCIe 3.0. This enables quicker boot-up and app load times with OS or application drives
