ASRock B850 Steel Legend WiFi VS MSI MAG B850 Tomahawk Max WiFi

At their core, the ASRock B850 Steel Legend WiFi and the MSI MAG B850 Tomahawk Max WiFi share an almost identical foundation: both use the AM5 socket with a B850 chipset, arrive in a standard ATX form factor, and offer the same modern connectivity stack — Wi-Fi 7 (backward-compatible down to Wi-Fi 4), Bluetooth 5.4, and HDMI 2.1. Both also support overclocking, include RGB lighting, feature a dual BIOS for firmware redundancy, and carry a 3-year warranty. For most buyers, this shared profile means either board fits the same build types equally well.

The only meaningful differentiator in this group is Easy to reset BIOS: the MSI supports it, the ASRock does not. In practice, this matters most during failed overclocking attempts or a botched firmware update — having a dedicated, tool-free BIOS reset mechanism (typically a physical button) can save a builder from a frustrating recovery process, especially when no compatible CPU is on hand to boot into the UEFI normally. The physical dimensions are technically different (244 mm vs 243.8 mm height, 305 mm vs 304.8 mm width), but the sub-millimeter gap is entirely irrelevant for case compatibility.

Based strictly on the general specs provided, the MSI MAG B850 Tomahawk Max WiFi holds a narrow but real-world advantage thanks to its BIOS reset support — a small convenience feature that can become critically important at the worst possible moment. Everything else in this category is a dead heat.

Both the ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi support a maximum memory amount of 256GB, offering ample space for memory expansion. Each board has 4 memory slots and supports DDR5 memory, with dual memory channels for better performance. When it comes to overclocked RAM speed, the ASRock board supports up to 8000 MHz, while the MSI board can handle a slightly higher overclocked speed of 8400 MHz.

Both motherboards do not support ECC memory, meaning they are not designed for error-correcting code memory, typically found in systems that require high levels of data integrity. Aside from that, both boards share identical memory slots, DDR version, and memory channel configurations.

In summary, while both motherboards are very similar in terms of memory capabilities, the MSI model offers a marginally higher overclocked RAM speed, while both share the same maximum memory capacity and lack ECC support.

The ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi both offer a variety of USB ports, with some differences in the distribution of USB 3.2 Gen 1 and Gen 2 ports. The ASRock model has 2 USB 3.2 Gen 2 USB-A ports and 3 USB 3.2 Gen 1 USB-A ports, while the MSI model has the same number of USB 3.2 Gen 2 USB-A ports (2) but only 1 USB 3.2 Gen 1 USB-A port. Both boards also feature 2 USB 3.2 Gen 2 USB-C ports, though the MSI board has one more USB-C port (3) compared to the ASRock board's 2.

Both motherboards come with 4 USB 2.0 ports and do not feature any USB 3.2 Gen 2x2, USB 4, or Thunderbolt ports. Each board includes an HDMI output, but neither model offers DisplayPort outputs, DVI outputs, or VGA connectors. The RJ45 Ethernet port is present on both models, with no differences in this regard.

As for additional connectivity options, both motherboards support USB Type-C, and neither has PS/2 or eSATA ports. The MSI board stands out slightly with an additional USB 3.2 Gen 2 USB-C port, but overall, both motherboards offer similar port setups for everyday use and connectivity.

Both the ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi feature a similar set of connectors, including 4 USB 3.2 Gen 1 ports, 4 USB 2.0 ports, and 4 SATA 3 connectors. Both boards also offer 4 M.2 sockets for high-speed storage options. In terms of expansion, they both support 4 USB 3.0 ports through expansion, ensuring additional connectivity flexibility.

The ASRock board provides 6 fan headers, while the MSI board offers a slightly higher count of 8 fan headers, allowing for more cooling options. Both motherboards include a TPM connector, which can be used for security features, and neither has an mSATA connector. Additionally, neither board supports U.2 sockets or SATA 2 connectors.

Overall, while the ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi are quite similar in terms of connectors, the MSI model stands out with its additional fan headers, offering a bit more flexibility for cooling system configurations.

The ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi both feature one PCIe 4.0 x16 slot and one PCIe 5.0 x16 slot, offering strong expansion capabilities for modern GPUs and other high-bandwidth devices. Neither board includes a PCIe 3.0 x16 slot or any PCI slots, limiting support for older expansion cards. The ASRock board, however, does not provide any PCIe x1, x4, or x8 slots.

In contrast, the MSI board includes a PCIe x1 slot, giving it a slight edge in terms of expansion options for low-profile add-on cards, such as network or sound cards. Both motherboards are similar in their lack of PCIe x4 and x8 slots, which are often used for additional storage controllers or other specialized expansions.

Overall, the expansion slot configurations of both boards are quite similar, but the MSI model offers a bit more flexibility with its additional PCIe x1 slot, which the ASRock board does not have.

The ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi both offer 7.1-channel audio, providing rich sound quality for immersive experiences. Both motherboards feature S/PDIF Out ports for digital audio output, ensuring high-quality audio transmission. Additionally, both boards include 2 audio connectors for connecting external audio devices.

One notable difference between the two is the Signal-to-Noise ratio (DAC). The ASRock board offers a higher Signal-to-Noise ratio of 130 dB, compared to the MSI board's 120 dB. This means the ASRock model may deliver a slightly cleaner audio experience, with less noise interference.

Overall, both boards offer comparable audio features, with the ASRock model providing a marginally higher Signal-to-Noise ratio for better audio quality.

Both the ASRock B850 Steel Legend WiFi and MSI MAG B850 Tomahawk Max WiFi support the same RAID configurations, including RAID 1 (mirroring) and RAID 10 (1+0), allowing users to set up redundant storage arrays for data protection and improved performance. Both models also support RAID 0 (striping) for performance boosts, but neither supports RAID 5 (striping with parity) or RAID 0+1 (a combination of RAID 0 and RAID 1), limiting their options for data redundancy and fault tolerance beyond RAID 1 and 10.

Overall, the storage features for both motherboards are identical, with both supporting RAID 1, RAID 10, and RAID 0, but excluding RAID 5 and RAID 0+1 configurations.
