Built to Push Boundaries, Not Temperatures

The MSI PRO B840M-P Wi-Fi 6E keeps your system running at full throttle with Frozr Guard cooling — an extended heatsink, 7W/mK MOSFET thermal pads, and choke thermal pads that work together to banish heat before it ever slows you down. Whether you’re deep in a gaming session or crunching through a heavy workload, this board stays cool so you never have to.

Plug In, Power Up, Play Instantly

With Wi-Fi 6E delivering up to 2.4Gbps across 6GHz bands and Realtek 2.5G LAN keeping your wired connection rock solid, lag simply isn’t part of your vocabulary. PCIe 4.0 and dual Lightning Gen 4 x4 M.2 slots mean your storage and GPU are always feeding data at blistering speeds — perfect for streaming, online gaming, and content creation without compromise.

Snap It In, Switch It Up

MSI’s EZ DIY ecosystem — including EZ M.2 Clip II, EZ PCIe Clip II, and EZ Antenna — means upgrading your rig is a matter of minutes, not frustration. No extra tools, no fiddly screws, no headaches. Spend more time doing what you built this system for, and less time wrestling with it.
