  Performance
  
  
  Robust power design - PRIME B850-PLUS WIFI 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.
  
  Six-layer PCB design - The multi-layered printed circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and provide the CPU with more overclocking headroom.
  
  Power Saving - The Power Saving function contains several settings to easily optimize power consumption and maximize energy savings. You can enable a CPU power limit, darken Aura lighting and set the fan profile to a Power Saving mode. You can also toggle the Power Saver plan that is built into Microsoft Windows.
  
  Digi+ VRM control - The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings.
  
  
  
  
  
  
  
  
  
  Enhanced Memory & Storage Performance
  
  
  Enhanced DDR5 Performance - Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B850-PLUS WIFI 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 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 128 Gbps) - PRIME B850-PLUS WIFI 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.
  
  
  
   
  
   
  
   
  
   
  
  
   
  
  
  Cooler by design
  
  
  
  The PRIME B850-PLUS WIFI motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.
  
  
  
  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.
  
  
  
  
  
  
  
   
  
  Empowering connections
  
   
  This motherboard offers a versatile range of connectivity, including support for WiFi 6E, PCIe 5.0 slot and an arsenal of USB ports which includes Type-C® connections.
