ASRock B850M Steel Legend WiFi VS MSI B850M Gaming Plus Wi-Fi

At the platform level, the ASRock B850M Steel Legend WiFi and the MSI B850M Gaming Plus Wi-Fi are built on identical foundations: both use the AM5 socket with a B850 chipset, adopt a Micro-ATX form factor, and share the same wireless stack — Wi-Fi 7 (802.11be) with backwards compatibility down to Wi-Fi 4, plus Bluetooth 5.4. They also both support overclocking, include RGB lighting, feature a dual BIOS, and carry a 3-year warranty. For the vast majority of build decisions, these two boards start from the same place.

The one meaningful differentiator in this group is BIOS accessibility: the MSI offers easy BIOS reset, while the ASRock does not. In practice, this matters most when recovering from a failed overclock or a misconfigured firmware setting — a physical reset button or a dedicated clear-CMOS mechanism means you can recover without removing the motherboard battery or consulting the manual. For builders who plan to push memory or CPU frequencies, or who are less experienced with BIOS recovery procedures, this is a genuine quality-of-life advantage. The dimensional difference (244 mm vs. 243.8 mm) is purely cosmetic and has no real-world impact on fitment.

Based strictly on the general specs provided, the MSI B850M Gaming Plus Wi-Fi holds a narrow but practical edge, solely due to its easy BIOS reset capability. Everything else is a tie.

Both the ASRock B850M Steel Legend WiFi and the MSI B850M Gaming Plus Wi-Fi offer strong memory specifications, though there are a few key differences. Both motherboards support a maximum memory amount of 256GB and come with 4 memory slots, as well as dual memory channels. They also support DDR5 memory version, ensuring high-speed performance for modern systems. Neither motherboard supports ECC memory.

When it comes to RAM speeds, the ASRock B850M Steel Legend WiFi can handle a maximum speed of 8000 MHz, with the same speed supported for overclocked RAM. In contrast, the MSI B850M Gaming Plus Wi-Fi supports a lower maximum RAM speed of 5600 MHz, but its overclocked RAM speed can reach 8200 MHz. This means the MSI motherboard offers a higher overclocked RAM speed, while the ASRock model has a higher base RAM speed.

In summary, the ASRock B850M Steel Legend WiFi excels in base RAM speed, while the MSI B850M Gaming Plus Wi-Fi offers more potential for overclocking memory speeds. Both motherboards are well-equipped for high-performance memory configurations.

The ASRock B850M Steel Legend WiFi and the MSI B850M Gaming Plus Wi-Fi offer similar port configurations, though there are a few key differences. Both motherboards feature HDMI outputs and DisplayPort outputs, along with a single RJ45 port for Ethernet connectivity. Both also support USB Type-C, but the ASRock model has 1 USB 3.2 Gen 2 Type-C port, while the MSI model has 2 USB 3.2 Gen 2 Type-C ports, giving it slightly more flexibility for modern USB-C devices.

In terms of USB ports, the ASRock B850M Steel Legend WiFi has 1 USB 3.2 Gen 2 (USB-A) port, 2 USB 3.2 Gen 1 (USB-A) ports, and 4 USB 2.0 ports. The MSI B850M Gaming Plus Wi-Fi, on the other hand, provides 3 USB 3.2 Gen 2 (USB-A) ports and 3 USB 3.2 Gen 1 (USB-A) ports but lacks USB 2.0 ports entirely. Neither board offers USB 3.2 Gen 2x2, USB 4, or Thunderbolt ports, and both are free of VGA and PS/2 connectors.

Overall, both motherboards offer a solid range of connectivity options, but the MSI board offers a greater number of USB-A and Type-C ports, while the ASRock model has more USB 2.0 ports for older devices.

The ASRock B850M Steel Legend WiFi and MSI B850M Gaming Plus Wi-Fi both provide similar connector options, with a few differences in expansion capabilities. Both motherboards offer 4 SATA 3 connectors and 5 fan headers, ensuring solid support for storage devices and cooling. Both also feature TPM connectors for enhanced security. Neither motherboard includes U.2 or mSATA connectors, and neither has SATA 2 connectors.

When it comes to expansion ports, the ASRock board offers more flexibility with 4 USB 3.2 Gen 1 ports and 4 USB 3.0 ports (through expansion), compared to the MSI board, which has only 2 USB 3.2 Gen 1 ports and 2 USB 3.0 ports (through expansion). Additionally, the ASRock board provides 3 M.2 sockets for high-speed storage devices, while the MSI board has 2 M.2 sockets.

In summary, the ASRock B850M Steel Legend WiFi offers more expansion options for USB ports and M.2 sockets, while both motherboards share similar basic connectors such as SATA and fan headers.

The ASRock B850M Steel Legend WiFi and MSI B850M Gaming Plus Wi-Fi share similar expansion slot configurations, but with a few differences. Both motherboards feature a PCIe 5.0 x16 slot and a PCIe x4 slot, which are important for modern high-performance graphics and storage cards. Neither board has PCIe 4.0 x16 slots, PCIe 3.0 x16 slots, or PCIe 2.0 x16 slots, and both boards lack PCI slots.

The key difference comes in the PCIe x1 slots. The ASRock B850M Steel Legend WiFi has no PCIe x1 slots, while the MSI B850M Gaming Plus Wi-Fi offers one PCIe x1 slot, which allows for additional expansion options for smaller add-in cards such as network adapters or sound cards.

Overall, the two motherboards are similar in most aspects, but the MSI board offers a slight advantage in terms of expansion with its single PCIe x1 slot.

The ASRock B850M Steel Legend WiFi and MSI B850M Gaming Plus Wi-Fi have identical audio specifications. Both motherboards support 7.1 audio channels, providing high-quality sound for gaming and multimedia experiences. Neither board includes an S/PDIF Out port, and both feature 3 audio connectors for various audio device connections.

In summary, both products offer the same audio capabilities, with no differences in their support for audio channels, S/PDIF Out, or audio connectors.

Both the ASRock B850M Steel Legend WiFi and MSI B850M Gaming Plus Wi-Fi offer the same RAID support features. They both support RAID 1, RAID 10 (1+0), and RAID 0, making them suitable for a variety of storage configurations. However, neither motherboard supports RAID 5 or RAID 0+1, meaning they both lack the ability to create those specific RAID levels.

In summary, the storage capabilities are identical between the two motherboards, with both supporting RAID 1, RAID 10 (1+0), and RAID 0 but not RAID 5 or RAID 0+1.
