MSI B840 Gaming Plus WiFi VS MSI Pro B840-P WiFi

At the foundational level, the MSI B840 Gaming Plus WiFi and the MSI Pro B840-P WiFi are built on an identical platform: both use the AM5 socket with the B840 chipset, adopt the standard ATX form factor, and share the same physical dimensions of 304.8 × 243.8 mm. This means they are drop-in compatible with the same cases and CPU lineup, and neither board offers a platform-level advantage over the other.

Connectivity features are also a perfect match across both boards. Each supports the full Wi-Fi 7 (802.11be) stack — backward compatible down to Wi-Fi 4 — along with Bluetooth 5.4, ensuring low-latency wireless peripherals and future-ready networking. Both also include HDMI 2.1 output, dual BIOS for resilience against failed updates, an easy BIOS reset mechanism, and overclocking support. A 3-year warranty applies to both, which is a reassuring commitment at this tier.

Given that every single spec in this group is identical, this comparison results in a complete tie. Neither the Gaming Plus WiFi nor the Pro B840-P WiFi holds any general-spec advantage over the other. The meaningful differences between these two boards will come down to other specification groups — such as memory support, expansion slots, I/O, or audio — rather than anything in their general configurations.

The MSI B840 Gaming Plus WiFi and MSI Pro B840-P WiFi both offer identical memory specifications. Both motherboards support a maximum memory amount of 256GB and are capable of running RAM at a maximum speed of 5600 MHz. Additionally, both products can achieve an overclocked RAM speed of 8000 MHz. They each feature 4 memory slots and support DDR5 memory with dual memory channels. Neither motherboard supports ECC memory.

Since the memory specifications are the same across both models, there are no differences in terms of their memory capabilities. Users can expect the same performance in terms of RAM capacity, speed, and slot configuration for either product.

Overall, the memory features of the MSI B840 Gaming Plus WiFi and the MSI Pro B840-P WiFi are identical, ensuring equivalent memory support on both boards.

The MSI B840 Gaming Plus WiFi and the MSI Pro B840-P WiFi offer the same set of ports, providing identical options for connectivity. Both motherboards come with 1 USB 3.2 Gen 2 port (USB-A), 2 USB 3.2 Gen 1 ports (USB-A), and 1 USB 3.2 Gen 2 port (USB-C). They also feature 4 USB 2.0 ports and lack USB 3.2 Gen 2x2, USB 4 40Gbps, or USB 4 20Gbps ports. Neither motherboard includes Thunderbolt 4 or Thunderbolt 3 ports.

Both products have an HDMI output, but they do not offer DisplayPort outputs, eSATA ports, or DVI outputs. Additionally, neither model includes a VGA connector, and both lack PS/2 ports.

The RJ45 ports and the USB Type-C connectivity are the same on both boards, and the overall configuration of ports is identical, ensuring that both motherboards offer the same functionality in terms of connectivity options.

The MSI B840 Gaming Plus WiFi and MSI Pro B840-P WiFi have identical connector specifications. Both motherboards provide 2 USB 3.2 Gen 1 ports and 4 USB 2.0 ports through expansion. Additionally, both have 4 SATA 3 connectors and 6 fan headers. They each feature 2 M.2 sockets and 2 USB 3.0 ports through expansion.

Both products also have a TPM connector and lack U.2 sockets, mSATA connectors, and SATA 2 connectors. There are no differences in the connector configurations between the two models.

As a result, users will experience the same expansion and connectivity options on both the MSI B840 Gaming Plus WiFi and the MSI Pro B840-P WiFi when it comes to connectors.

The MSI B840 Gaming Plus WiFi and MSI Pro B840-P WiFi have identical expansion slot configurations. Both motherboards feature 1 PCIe 4.0 x16 slot and 1 PCIe 3.0 x16 slot, as well as 3 PCIe x1 slots. Neither product includes PCI slots, PCIe 2.0 x16 slots, PCIe x4 slots, or PCIe x8 slots.

With these shared specifications, both models offer the same options for expansion in terms of PCIe slots. There are no differences in the available expansion slot types between the two products.

As a result, the expansion capabilities of the MSI B840 Gaming Plus WiFi and the MSI Pro B840-P WiFi are identical, offering the same slot configurations for users to install additional components.

The MSI B840 Gaming Plus WiFi and MSI Pro B840-P WiFi both feature identical audio specifications. Both motherboards support 7.1 audio channels and do not have an S/PDIF Out port. They are equipped with 3 audio connectors each.

Since these audio specifications match across both models, there are no differences in audio functionality or available connectors between the MSI B840 Gaming Plus WiFi and the MSI Pro B840-P WiFi.

As a result, users will experience the same audio performance and connectivity on both motherboards.

The MSI B840 Gaming Plus WiFi and MSI Pro B840-P WiFi both support RAID 1 and RAID 0, allowing for redundancy or performance benefits in storage configurations. However, the MSI B840 Gaming Plus WiFi does not support RAID 10 (1+0) or RAID 0+1, while the MSI Pro B840-P WiFi does support RAID 10 (1+0) in addition to RAID 1 and RAID 0.

Both motherboards do not support RAID 5 or RAID 0+1, with RAID 5 being unsupported on both models.

Therefore, while both motherboards share some RAID support, the MSI Pro B840-P WiFi offers an additional RAID 10 (1+0) configuration not available on the MSI B840 Gaming Plus WiFi.
