Asus Prime B840-Plus WiFi VS MSI Pro B840-P WiFi

Both boards share the same foundational identity: AM5 socket, B840 chipset, standard ATX form factor, and near-identical dimensions — a difference of just 0.2 mm in each direction. They also match on every major feature checkbox: Wi-Fi, Bluetooth, HDMI 2.1, RGB lighting, dual BIOS, easy BIOS reset, and overclocking support. For most buyers, this common ground covers everything that matters at a glance.

The real differentiation sits in wireless connectivity. The MSI Pro B840-P WiFi supports Wi-Fi 7 (802.11be), while the Asus Prime B840-Plus WiFi tops out at Wi-Fi 6E. In practice, Wi-Fi 7 delivers significantly higher theoretical throughput and lower latency — relevant if you own a Wi-Fi 7 router today or plan to upgrade soon. Similarly, the MSI edges ahead with Bluetooth 5.4 versus 5.3 on the Asus; the newer version brings modest improvements in connection stability and power efficiency, though the real-world impact is subtle for most users.

On general specs alone, the MSI Pro B840-P WiFi holds a clear edge thanks to its newer wireless stack. Both boards carry a 3-year warranty and are otherwise functionally equivalent in this category, so if future-proofing your wireless connectivity matters — particularly Wi-Fi 7 readiness — the MSI is the stronger pick here.

The Asus Prime B840-Plus WiFi and MSI Pro B840-P WiFi both support DDR5 memory with 4 memory slots and 2 memory channels, making them suitable for modern memory configurations. The maximum supported memory differs, with the Asus board supporting up to 192GB, while the MSI board allows for a higher maximum of 256GB.

In terms of overclocked RAM speeds, the Asus Prime B840-Plus WiFi supports a maximum of 7600 MHz, whereas the MSI Pro B840-P WiFi offers a slightly higher maximum of 8000 MHz. Both motherboards do not support ECC memory, ensuring they are aimed at general use and gaming setups rather than specialized workloads requiring error-correcting memory.

While both motherboards are quite similar in their base memory features, the key difference lies in their maximum memory capacity and overclocked RAM speed, with the MSI board offering higher performance potential in these areas.

The Asus Prime B840-Plus WiFi and MSI Pro B840-P WiFi have similar port configurations, with both offering a mix of USB 3.2 Gen 2 and Gen 1 ports, including one USB 3.2 Gen 2 USB-A port and one USB 3.2 Gen 2 USB-C port. Both motherboards also feature two USB 3.2 Gen 1 USB-A ports and four USB 2.0 ports, ensuring flexibility for a variety of devices. Neither of these boards includes USB 3.2 Gen 2x2, USB 4, or Thunderbolt ports.

Both boards are equipped with an HDMI output, though the Asus model provides a DisplayPort output, while the MSI version does not. They both include one RJ45 port for network connectivity. In terms of video output, neither motherboard has a VGA connector, and neither features PS/2 or eSATA ports.

Overall, the port offerings are quite similar between the two models, with the key distinction being the DisplayPort output on the Asus board, which the MSI board lacks. Both also support USB Type-C, with no significant differences in the USB configuration.

The Asus Prime B840-Plus WiFi and MSI Pro B840-P WiFi share several similar features in their connectors. Both motherboards offer two USB 3.2 Gen 1 ports and four USB 2.0 ports through expansion, as well as two USB 3.0 ports through expansion. They also come with four SATA 3 connectors and six fan headers, providing good support for additional storage and cooling options.

The Asus board includes three M.2 sockets, whereas the MSI board has two M.2 sockets. Both motherboards feature a TPM connector, while neither includes mSATA connectors or U.2 sockets. Additionally, both motherboards do not support SATA 2 connectors.

Overall, the main difference between the two products in this group is the number of M.2 sockets, with the Asus board offering one more M.2 socket than the MSI board. All other connector features are identical across both models.

The Asus Prime B840-Plus WiFi and MSI Pro B840-P WiFi have some similarities and differences in their expansion slot configurations. Both motherboards feature one PCIe 4.0 x16 slot, but the Asus model includes three PCIe 3.0 x16 slots, while the MSI board only has one. The MSI board, however, provides three PCIe x1 slots, whereas the Asus board does not have any PCIe x1 slots.

Neither of the boards includes PCIe x4, PCIe x8, or PCI slots. Both motherboards also do not have PCIe 2.0 x16 slots. Neither motherboard features a PCIe 5.0 x16 slot.

Overall, the Asus board offers more PCIe 3.0 x16 slots, while the MSI board compensates with more PCIe x1 slots, providing different options depending on your expansion needs.

Both the Asus Prime B840-Plus WiFi and MSI Pro B840-P WiFi offer similar audio features, with both supporting 7.1 audio channels. Neither motherboard includes an S/PDIF Out port. Both boards also feature three audio connectors, providing the same connectivity options for audio devices.

There are no differences between the two products in terms of their audio capabilities, as both offer the same number of audio channels, connectors, and lack of S/PDIF Out support.

Overall, the audio specifications for these two motherboards are identical, offering equivalent functionality for users seeking standard audio performance.

The Asus Prime B840-Plus WiFi and MSI Pro B840-P WiFi both support RAID 1, RAID 10 (1+0), and RAID 0 configurations, providing flexibility for various storage setups. However, the Asus board also supports RAID 5, while the MSI board does not. Neither of the boards supports RAID 0+1, meaning users won’t be able to use this particular RAID configuration on either motherboard.

In terms of RAID support, the primary difference between the two models is the inclusion of RAID 5 on the Asus Prime B840-Plus WiFi, which offers an additional level of data redundancy compared to the MSI Pro B840-P WiFi.

Overall, while both boards offer the most common RAID configurations, the Asus board provides slightly more storage options due to its support for RAID 5.
