MSI Pro B840-P WiFi

Manufacturer: MSI

The MSI Pro B840-P WiFi is an ATX form factor motherboard built around AMD's AM5 socket and the B840 chipset. It comes equipped with Wi-Fi 7 (802.11be) and Bluetooth 5.4 out of the box, making it a capable option for wireless connectivity without requiring additional expansion cards. The board also includes RGB lighting, a clear CMOS button for straightforward BIOS resets, and dual BIOS support for added resilience during firmware updates.

On the memory side, the board provides four DDR5 slots across two channels, supporting up to 256GB at stock speeds of 5600 MHz and up to 8000 MHz when overclocked. Storage options include two M.2 sockets and four SATA 3 connectors, with RAID 0, 1, and 10 configurations supported. Expansion is handled by one PCIe 4.0 x16 slot, one PCIe 3.0 x16 slot, and three PCIe x1 slots. The rear I/O panel offers a mix of USB ports including USB 3.2 Gen 2 Type-A and Type-C, four USB 2.0 ports, HDMI 2.1 output, and a single RJ45 ethernet jack, complemented by a 7.1-channel audio solution with three audio connectors. The board carries a three-year warranty.

Pros

Supports Wi-Fi 7 alongside all previous Wi-Fi generations down to Wi-Fi 4, providing broad wireless compatibility
Dual BIOS adds a layer of protection against failed firmware updates
DDR5 memory can be overclocked up to 8000 MHz, with four slots accommodating up to 256GB total
Six fan headers give solid flexibility for managing cooling across the system
Includes both a TPM connector and a clear CMOS button, aiding security setup and BIOS recovery
RAID 0, 1, and 10 configurations are supported, offering options for both storage performance and data redundancy

Cons

No PCIe 5.0 x16 slot available, limiting future high-bandwidth expansion card compatibility
ECC memory is not supported, ruling out error-correcting RAM configurations
Only two M.2 sockets are present, which may feel restrictive for storage-heavy builds
No S/PDIF Out port for digital audio passthrough
USB 4, Thunderbolt 3, and Thunderbolt 4 ports are entirely absent from the rear I/O

Who is this for?

This board is a solid fit for users building a capable AM5-based desktop system who want built-in Wi-Fi 7 without relying on a separate adapter. The ATX form factor and six fan headers make it well suited for standard mid-tower builds where airflow management matters. With DDR5 support up to 256GB and overclocked RAM speeds reaching 8000 MHz, it also appeals to enthusiasts who want headroom for memory tuning. The inclusion of dual BIOS, a TPM connector, and RAID 0/1/10 support makes it a reasonable choice for users who prioritize system reliability and basic data redundancy in a home office or workstation environment.

Who is this NOT for?

Users who need Thunderbolt or USB 4 connectivity for high-speed peripherals or external storage will find this board lacking, as none of those interfaces are present. It is also not well suited for professionals requiring ECC memory support, such as those running memory-sensitive workloads where data integrity is critical. Additionally, builders planning to install the latest PCIe 5.0 graphics cards or NVMe drives at full bandwidth will be limited, as only a PCIe 4.0 x16 slot is available and no PCIe 5.0 slot is included.

Final Verdict

The MSI Pro B840-P WiFi is a well-rounded ATX motherboard for the AM5 platform that covers the essentials without overreaching. Its standout feature is integrated Wi-Fi 7 with Bluetooth 5.4, which removes the need for an add-in card and keeps the build clean. DDR5 support with overclocking headroom up to 8000 MHz, dual BIOS protection, and RAID functionality round out a feature set that serves mainstream desktop builders and light workstation users alike. That said, the absence of PCIe 5.0, USB 4, Thunderbolt, and ECC memory support means it is not positioned for users with demanding peripheral or professional reliability requirements. For those building a capable, connectivity-focused AM5 system without those specific needs, the MSI Pro B840-P WiFi delivers a coherent and practical package.
