Asus TUF Gaming B850-Plus WiFi VS Asus TUF Gaming B850M-Plus WiFi

Both the Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi share the same foundation: an AM5 socket with a B850 chipset, dual BIOS, RGB lighting, HDMI 2.1, and a 3-year warranty. For day-to-day use, this means both boards are equally capable as a platform base, support the same CPU lineup, and offer the same video output quality and reliability features.

The most decisive split between the two is form factor. The B850-Plus is a full ATX board (305 mm wide), while the B850M-Plus is Micro-ATX (244 mm wide), despite sharing the same 244 mm height. In practice, the ATX board fits only in mid-tower or full-tower cases, while the Micro-ATX opens up smaller, more compact builds. If case size is a constraint, the B850M-Plus is the only viable option here. The wireless stack also diverges: the B850-Plus supports Wi-Fi 7 (802.11be) and Bluetooth 5.4, whereas the B850M-Plus tops out at Wi-Fi 6E and Bluetooth 5.3. Wi-Fi 7 delivers significantly higher theoretical throughput and lower latency on compatible routers, and Bluetooth 5.4 brings minor stability and energy efficiency improvements over 5.3.

The B850-Plus WiFi has a clear edge in wireless connectivity thanks to Wi-Fi 7 and the newer Bluetooth version — meaningful for users with a modern router or many wireless peripherals. However, if you are building in a compact case or do not yet own a Wi-Fi 7 router, the B850M-Plus WiFi is the more practical pick, sacrificing only future-proofing on the wireless side in exchange for a smaller footprint.

The memory specifications for the Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi are identical. Both motherboards support a maximum memory amount of 192GB and have 4 memory slots. They both also support DDR5 memory with a maximum overclocked RAM speed of 8000 MHz and feature dual memory channels. Neither model supports ECC memory.

With matching memory capabilities, users can expect similar performance when it comes to memory configuration and capacity on both motherboards.

The Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi share many similarities when it comes to their port configurations, though there are a few small differences. Both motherboards offer 3 USB 3.2 Gen 2 (USB-A) ports, 4 USB 3.2 Gen 1 (USB-A) ports, 1 USB 3.2 Gen 2x2 port, and 1 DisplayPort output. They also both feature HDMI output, 1 RJ45 port, and a USB Type-C port. Neither motherboard includes any USB 4 or Thunderbolt ports, nor do they offer eSATA, DVI, or VGA connectors.

The main difference between the two products is in the number of USB 2.0 ports. The B850-Plus WiFi has 2 USB 2.0 ports, while the B850M-Plus WiFi has 4 USB 2.0 ports. Otherwise, the port configurations are identical, including the absence of PS/2 ports and the lack of VGA connectors on both models.

In summary, both motherboards offer the same range of modern connectivity options, with the B850M-Plus WiFi having a slight edge in the number of USB 2.0 ports.

The Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi are quite similar in terms of connectors, with only a small difference between them. Both motherboards offer 2 USB 3.2 Gen 1 ports (through expansion), 4 USB 2.0 ports (through expansion), and 2 USB 3.0 ports (through expansion). They also feature 4 SATA 3 connectors and 3 M.2 sockets, with no U.2 or mSATA connectors available on either model.

The key distinction is in the number of fan headers: the B850-Plus WiFi has 6 fan headers, while the B850M-Plus WiFi has 5 fan headers. Additionally, neither motherboard includes a TPM connector.

In conclusion, the main difference between these two models lies in the number of fan headers, with the B850-Plus WiFi providing one additional header for greater cooling expansion.

The expansion slot configurations of the Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi show some key differences in the types of PCIe slots available. The B850-Plus WiFi has 1 PCIe 4.0 x16 slot and 1 PCIe 5.0 x16 slot, along with 2 PCIe x1 slots. In contrast, the B850M-Plus WiFi has 1 PCIe 5.0 x16 slot but no PCIe 4.0 x16 slot, and it includes only 1 PCIe x1 slot.

Neither motherboard features any PCI slots, PCIe 2.0 x16 slots, PCIe x4 slots, or PCIe x8 slots, and both models have no PCIe 3.0 x16 slots. The B850-Plus WiFi stands out with its additional PCIe 4.0 x16 slot, offering a bit more flexibility for expansion.

In summary, the main difference between these two motherboards is the extra PCIe 4.0 x16 slot available on the B850-Plus WiFi, which provides more options for users who need additional high-speed expansion slots.

Both the Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi have the same high-quality audio specifications, with both offering a signal-to-noise ratio (DAC) of 120 dB and supporting 7.1 audio channels. They also each have 5 audio connectors, providing a solid range of options for audio setups.

The key difference lies in the presence of an S/PDIF Out port: the B850M-Plus WiFi includes this feature, while the B850-Plus WiFi does not.

In summary, the main difference between the two models is the inclusion of an S/PDIF Out port on the B850M-Plus WiFi, which can be useful for digital audio output to external devices.

The Asus TUF Gaming B850-Plus WiFi and the Asus TUF Gaming B850M-Plus WiFi offer identical storage RAID support options. Both motherboards support RAID 1, RAID 10 (1+0), and RAID 5, providing flexibility for various storage configurations. Neither model supports RAID 0+1.

With the same RAID capabilities, both motherboards offer equivalent storage options for users looking to set up redundant or high-performance disk arrays.
