Overview
ASUS Prime series motherboards are expertly engineered to unleash the full potential of AMD Ryzen 9000 series processors. The PRIME B850-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 B850-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 B850-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 B850-PLUS WIFI-CSM offers extensiveAMD Extended Profiles for Overclocking (EXPO) support and a wide array of UEFI settings for further performance tweaks. Three M.2 slots (up to 128 Gbps) PRIME B850-PLUS WIFI-CSM offers a total of three M.2 slots, including one that supports data-transfer speeds of up to 128 Gbps via PCIe 5.0, and two that support PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives. ASUS Fan Xpert 2+ ASUS Fan Xpert 2+ software provides comprehensive control over fans. An Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS.
