Product information

Description

PRO B840M-P WIFI6E offers a simple silver design that fits both white and black PC builds. This MSI PRO Series micro-ATX motherboard supports AMD Socket AM5 processors including Ryzen 7000, 8000 and 9000 series, and provides DDR5 memory support up to 256 GB, multiple storage options including M.2 and SATA III, plus advanced connectivity with Wi‑Fi 6E and 2.5 Gigabit Ethernet.

Advantages

The motherboard features a direct 7+2+1 digital power design with an 8‑pin CPU connector for stable power delivery under heavy loads. An optimized PCB and extended heatsink improve bandwidth, transfer reliability and thermal dissipation. High‑performance 7 W/mK MOSFET thermal pads and additional choke pads help maintain stability when all cores run at high speed. Built‑in Wi‑Fi 6E (with EZ Antenna) and 2.5G LAN provide high‑bandwidth, low‑latency network connectivity.

Suitable for

  • Building compact high-performance desktop PCs (micro‑ATX)
  • Productivity and multitasking workstations using AMD Ryzen 7000/8000/9000 series
  • Systems requiring fast networking with Wi‑Fi 6E or 2.5 Gigabit Ethernet
  • Storage‑heavy setups using multiple M.2 and SATA III drives

Key specifications

  • Processor socket: AMD Socket AM5 — supports Ryzen 7000, 8000, 9000 series
  • Chipset: AMD B840
  • Form factor: Micro ATX
  • Memory: 4 × DDR5 DIMM slots, maximum 256 GB
  • Storage: M.2 and SATA III support; up to 6 storage drives supported
  • LAN & wireless: 2.5 Gigabit Ethernet, Wi‑Fi 6E (802.11ax), Bluetooth 5.3
  • Audio: Realtek ALC897, 7.1 channels
  • BIOS: UEFI AMI 256 Mbit, ACPI 6.5

How to use

Install a compatible AMD Socket AM5 processor and populate up to four DDR5 memory modules according to the motherboard user manual. Connect storage devices to M.2 slots or SATA III ports and attach the 8‑pin CPU power connector and 24‑pin ATX power cable from a compatible PSU. Configure BIOS/UEFI settings as needed for boot order, memory profiles and device configuration. For wireless networking, attach the EZ Antenna and enable Wi‑Fi in the operating system or BIOS.

Usage recommendations

For optimal thermal performance, ensure good airflow in the chassis and secure the extended heatsink clearance. Use updated BIOS firmware and drivers from MSI for best compatibility with Ryzen 7000/8000/9000 series CPUs and to enable Wi‑Fi 6E functions.
