The PRO B850-S WIFI6E is a business-oriented ATX motherboard with a 12 Duet Rail Power System, constructed around the latest AMD B850 chipset which supports AMD Ryzen 9000 / 8000 / 7000 series desktop processors, featuring PCIe 5.0 M.2, 2.5G LAN, Wi-Fi 6E and DDR5 that delivers the capacity to support a broad spectrum of both cutting-edge and innovative hardware.
The PRO B850-S WIFI6E motherboard supports AMD Ryzen 9000 / 8000 / 7000 Series processors.
With exclusive Core Boost technology and EZ OC Tuning functions, the PRO B850-S WIFI6E is able to sustain heavy CPU power loads to support system-demanding settings:
Frozr Guard: VRM heatsink, 7W/mK MOSFET thermal pads, and M.2 Shield Frozr for improved thermal dissipation.
Frozr Sync: Connect and synchronize cooling with strategically placed pin-headers - including CPU fan header (2A), Combo fan (3A, supports both pump fan and system fan) and system fans.
Frozr Control: Manage speeds and temperature for all fans of your system in MSI Center with Cooling Wizard and Frozr AI Cooling.
Memory Boost: A fully-isolated DDR circuit delivers pure data signals for optimal gaming and overclocking performance.
High-Efficiency Mode: Enabling High-Efficiency-Mode in the MSI BIOS increases memory bandwidth and reduces latency. Four different modes allow users to find out the optimal configuration based on the quality of their memory modules.
EXPO Profiles in the MSI BIOS are MSI OC LAB optimized and can be easily enabled with auto power settings for optimized memory speed and stability.
*1DPC 1R Max. overclocking frequency 8200+ MT/s, supports AMD EXPO.
MSI PCI Express Steel Armor slots are secured to the motherboard with extra solder points to support the weight of heavy graphics cards. When every advantage in games counts, Steel Armor also shields the point of contact from electromagnetic interference.
The PRO B850-S WIFI6E motherboard features MSI's M.2 slots:
The DIY Friendly designs optimize the assemble process and experience.
EZ PCIe Clip II: Allows for easy removal of the graphics card by pressing the tail-like lock with one finger, even in the cramped case spaces.
EZ M.2 Clip II: Install or remove the SSD with a simple push of the latch, without using any screws.
EZ Antenna: MSI's latest Wi-Fi antenna not only boasts a beautiful appearance but also features a magnetic design, making it easier to adjust the antenna's placement.
2.5G LAN: A Realtek 2.5Gbps LAN controller delivers a premium network experience.
Wi-Fi 6E: Features the Wi-Fi 6E solution (ultra-low latency, high-bandwidth) & Bluetooth 5.3 technology.
USB 10Gbps Type-C: Connect to devices and transfer files at high bandwidth rates.
HD Audio: 7.1-Channel High Definition Audio with Audio Boost.
