Product Overview

MSI PRO B840-S EVO WIFI6E ATX Motherboard

PRO B840-S EVO WIFI6E offers a simple design with a harmonious colour scheme that perfectly matches black PC builds. It is engineered with many exclusive features of MSI, a Wi-Fi 6E with EZ Antenna, 2.5G LAN, and PCIe 4.0 M.2 with M.2 Shield Frozr, ready for the AMD Ryzen™ 9000 series processors.


Ready For AI

MSI motherboards are engineered with advanced hardware and intelligent technologies to support the demanding performance needs of gaming, content creation, and AI-driven workloads. By integrating AI-powered features into both MSI Center and the BIOS, MSI makes system optimisation and performance management more intuitive than ever.

AI Engine intelligently detects your active applications and automatically applies optimised performance settings, helping create a smoother and more responsive user experience.

AI LAN Manager enhances network performance by prioritising bandwidth and reducing latency, delivering a faster and more stable online gaming and streaming experience.

Frozr AI Cooling automatically adjusts fan speeds based on system temperatures, ensuring efficient cooling, stable operation, and consistent high-performance output.

AI Boost is an MSI-exclusive feature that overclocks the NPU (Neural Processing Unit) to accelerate AI-based tasks and improve overall AI computing performance.


Direct 7-Phase Power

MSI equips the board with a 7+2+1 digital power design, 8-pin CPU power, and 6-layer PCB construction with 2oz copper for stability under load. Thermal features include 7W/mK MOSFET thermal pads, an enlarged heatsink area, pump fan support, and Frozr AI Cooling, which automatically adjusts fan behaviour based on CPU and GPU temperatures.


DDR5 - From Strength to Strength

The PRO B840-S EVO WIFI6E motherboard supports DDR5 memory with four DIMM slots in a dual-channel layout, and MSI highlights support for speeds up to 8000+ MT/s when overclocked. MSI also ties in its Memory Boost and low-latency tuning features to improve memory performance and responsiveness.


EZ DIY Features

MSI's EZ DIY approach makes installation and upgrades easier. Features like EZ PCIe Clip II, EZ M.2 Clip II, EZ Antenna, and EZ mounting details reduce the need for tools and simplify common build tasks.


Maximise Your Storage Options

For storage, the board offers M.2 Gen4 support for fast NVMe drives, along with SATA ports for additional drives, plus MSI's M.2 Shield Frozr to help keep SSD temperatures under control during heavy use.


Flawless Connection

The networking setup combines a Realtek 2.5G LAN port with Wi-Fi 6E and Bluetooth 5.3. MSI presents this as a high-speed, low-latency connection package for both wired and wireless use, with the Wi-Fi 6E solution designed to use the 6GHz band for cleaner, faster wireless performance.


Lightning GEN 4 PCI-E

MSI lightning Gen 4 PCI-E represents the bandwidth of a x16 interface to 64GB/s that has doubled compared to its previous generation.


Reinforced, Heavy Soldered Connections

MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points and support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor shields the point of contact from electromagnetic interference.


Front Type-C

MSI motherboards support USB Front Type-C that allows gamers to connect with the latest USB devices. Built up a system with MSI PC case to have the most convenient experience.


Mystic Light

Splash on some colour and vibrant RGB lighting effects using Mystic Light utility of MSI Center, which has million colours and fancy LED effects. Enjoy the full control and creativity of your PC's lighting with one software.


CLICK BIOS X

MSI's newly designed CLICK BIOS X offers an aesthetically pleasing and user-friendly experience. The new design ensures that users of all experience levels can quickly access and adjust system configurations with ease.


MSI Center

The all-new MSI Center brings together a comprehensive suite of MSI software utilities into one intuitive, centralised application. Easily monitor, customise, and optimise advanced motherboard features through a streamlined interface, giving you greater control over system performance, cooling, RGB lighting, networking, and more to unlock the full potential of your PC.
