SAPPHIRE PULSE B850M WIFI
The SAPPHIRE PULSE B850M WIFI motherboard, featuring the AMD B850 chipset and AM5 socket, comes in a compact Micro-ATX form factor measuring 244×244mm. It supports Ryzen 9000, 8000, and 7000 series processors, has four DDR5 slots for a maximum capacity of 256GB with overclocking up to 7600MHz, and offers modern connectivity including Wi-Fi 6, Bluetooth 5.3, two M.2 slots with PCIe 5.0 and PCIe 4.0 support, and advanced VRM and chipset cooling. The powerful 7+2+1 phase power delivery at 60A per phase eliminates throttling even with high-performance processors and, combined with the massive PULSE heatsink armour, keeps critical components at optimal temperatures. Thanks to its rich I/O interface with DisplayPort 1.2, HDMI 1.4, eight USB ports, and a 2.5 Gigabit Ethernet port, this motherboard is the ideal choice for building a compact yet powerful gaming or work system.

Support for high-performance AMD processors
The motherboard supports AMD Ryzen 9700X and 9800X3D processors without any performance limitations, even under full load. A robust power delivery system with a 7+2+1 phase configuration and 60A per phase ensures a stable and efficient power supply to all processor cores. The PULSE heatsink armour provides effective cooling for both the VRM and chipset, contributing to the long-term reliability of the entire system.
Memory subsystem with advanced overclocking
Four DDR5 slots in dual-channel mode enable the installation of up to 256GB of RAM, supporting frequencies up to 7600MHz when overclocked. The optimised dual memory slot design is engineered to achieve higher frequencies while maintaining maximum stability, giving users full control over system performance.
Fast storage options for demanding applications
The motherboard features two M.2 slots, one supporting PCIe 5.0 and the other PCIe 4.0, which provide high-speed interfaces and sufficient bandwidth for both data storage and system expansion. The PCIe 5.0 M.2 slot achieves read speeds of up to 10.08GB/s and write speeds of up to 10.20GB/s, while the PCIe 4.0 M.2 slot offers read speeds of 7.22GB/s and write speeds of 6.20GB/s. In addition, the motherboard includes four SATA connectors for connecting further storage devices.
Expansion slots for graphics cards and other components
Two PCIe slots are available. The main PCIe 4.0 ×16 slot is designed for the latest high-performance graphics cards, while the second PCIe 4.0 ×4 slot with an open-ended design is compatible with 10-gigabit network cards, sound cards, capture cards, and other expansions, providing flexible upgrade options.
Rich I/O interface and wireless connectivity
The motherboard is equipped with an integrated Wi-Fi 6 module and Bluetooth 5.3, enabling easy connection of peripherals without external adapters. The front USB headers provide modern connectivity for various devices. Protection against electrostatic discharge and humidity ensures the long-term reliability of all connectors.
Advanced visual effects and system tuning
The motherboard includes three 5V ARGB headers and five fan headers, which are compatible with TriXX-M software and Windows 11 Dynamic Lighting. This enables flexible and customisable visualisation of your case's backlighting. Debug LED indicators (DRAM – yellow, CPU – red, GPU – white, Boot – green) simplify system diagnostics and the quick identification of any issues during computer start-up.

Choosing a motherboard
When choosing a motherboard (also known as a mainboard), it is important to pay particular attention to the motherboard's socket type, format and chipset. These parameters are among the most important and ensure the board's compatibility with the processor, expansion cards and other components. The specific socket determines your choice of processor, while the other connectors will dictate the other components you need for your future computer.Specifications
