Asus TUF Gaming B860-Plus WiFi VS Asus TUF Gaming B860M-Plus WiFi

At their core, the Asus TUF Gaming B860-Plus WiFi and the B860M-Plus WiFi are built on the same foundation: identical LGA 1851 socket and B860 chipset, identical wireless capabilities up to Wi-Fi 7 and Bluetooth 5.4, and the same feature set including dual BIOS, easy BIOS reset, RGB lighting, and overclocking support. Even the warranty period and HDMI version are identical. For a user scanning this spec group, the two boards are functionally a mirror image of each other in almost every meaningful way.

The one and only differentiator here is form factor. The B860-Plus is a full ATX board measuring 305 × 244 mm, while the B860M-Plus is a Micro-ATX board at 244 × 244 mm — 61 mm narrower. In practice, this means the M-Plus fits into smaller Mid-Tower or Micro-ATX cases, making it the right pick for a more compact build. The trade-off is that a smaller PCB typically means fewer expansion slots and headers, which may matter depending on your planned configuration — though those details fall outside this spec group.

Edge: Tied on features; form factor decides the winner for your use case. If case size is not a constraint and you want maximum expandability headroom, the B860-Plus (ATX) has the physical advantage. If you are targeting a smaller, cleaner build, the B860M-Plus (Micro-ATX) delivers the exact same general feature set in a more compact footprint. Neither board holds an advantage in connectivity, wireless, or platform support within this group.

Both the Asus TUF Gaming B860-Plus WiFi and Asus TUF Gaming B860M-Plus WiFi support a maximum memory amount of 256GB, providing ample space for high-performance builds. They each have 4 memory slots and support dual memory channels, with DDR5 memory version compatibility. Neither model supports ECC memory, which is common for gaming and high-performance boards.

The two products differ slightly in overclocked RAM speed, with the B860-Plus WiFi supporting up to 8666 MHz, while the B860M-Plus WiFi can reach a higher overclocked speed of 8800 MHz. This difference in RAM speed could provide a slight edge in performance for the B860M-Plus WiFi in memory-intensive tasks that benefit from faster RAM speeds, though both speeds are quite high for gaming and general use.

Overall, the memory specifications are very similar between the two, with the primary difference being the slightly faster overclocked RAM speed of the B860M-Plus WiFi at 8800 MHz, compared to 8666 MHz on the B860-Plus WiFi.

The Asus TUF Gaming B860-Plus WiFi and Asus TUF Gaming B860M-Plus WiFi offer similar port configurations with a few key differences. Both boards feature 2 USB 3.2 Gen 2 ports (USB-A), 1 USB 3.2 Gen 2x2 port, and 1 RJ45 Ethernet port. Both also include an HDMI output, 1 DisplayPort output, and USB Type-C support. Neither board offers USB 4 or Thunderbolt ports, and both lack VGA connectors and PS/2 ports.

Where they differ is in their USB 3.2 Gen 1 ports (USB-A). The B860-Plus WiFi has 3 such ports, while the B860M-Plus WiFi has 4. Additionally, the B860-Plus WiFi includes 2 USB 2.0 ports, whereas the B860M-Plus WiFi only has 1. Both motherboards share 1 USB 3.2 Gen 2 (USB-C) port and lack eSATA, DVI, and Thunderbolt ports.

In summary, the key differences between the two are the number of USB 3.2 Gen 1 (USB-A) and USB 2.0 ports, with the B860M-Plus WiFi offering more of both. The rest of the port configurations are largely identical across the two models.

The Asus TUF Gaming B860-Plus WiFi and Asus TUF Gaming B860M-Plus WiFi share similar connector configurations, with both featuring 2 USB 3.2 Gen 1 ports, 1 USB-C 3.2 Gen 2 port, and 2 USB 2.0 ports through expansion. They also both provide 4 SATA 3 connectors, 2 USB 3.0 ports through expansion, and 3 M.2 sockets. Neither motherboard includes a U.2 socket, mSATA connector, or TPM connector, and both have 0 SATA 2 connectors.

The main difference between the two models is in the number of fan headers. The B860-Plus WiFi has 6 fan headers, while the B860M-Plus WiFi has 5 fan headers. This gives the B860-Plus WiFi a slight advantage in terms of cooling options for larger or more complex systems.

Overall, both motherboards are quite similar in terms of connectors, with the only notable difference being the number of fan headers, with the B860-Plus WiFi offering one more than the B860M-Plus WiFi.

The Asus TUF Gaming B860-Plus WiFi and Asus TUF Gaming B860M-Plus WiFi have differing configurations for expansion slots. The B860-Plus WiFi includes 1 PCIe 4.0 x16 slot and 1 PCIe 5.0 x16 slot, while the B860M-Plus WiFi has 1 PCIe 5.0 x16 slot but no PCIe 4.0 x16 slot. Both motherboards lack PCIe 3.0 x16 slots, PCIe 2.0 x16 slots, and PCI slots.

The B860-Plus WiFi also features 1 PCIe x1 slot, while the B860M-Plus WiFi does not include any PCIe x1 slots. Additionally, the B860M-Plus WiFi offers 1 PCIe x4 slot, which is absent on the B860-Plus WiFi.

In summary, the B860-Plus WiFi offers a PCIe 4.0 x16 slot and a PCIe x1 slot, while the B860M-Plus WiFi compensates with a PCIe x4 slot, but lacks a PCIe 4.0 x16 or PCIe x1 slot. Both boards share the inclusion of 1 PCIe 5.0 x16 slot.

The Asus TUF Gaming B860-Plus WiFi and Asus TUF Gaming B860M-Plus WiFi have identical audio specifications. Both motherboards support 7.1 audio channels, feature an S/PDIF Out port, and include 5 audio connectors.

There are no differences between the two products in terms of audio capabilities. Both provide the same number of channels, ports, and connectors, making them equally equipped for audio output.

In summary, the audio features of both the B860-Plus WiFi and the B860M-Plus WiFi are the same, with no distinction between them in this category.

The Asus TUF Gaming B860-Plus WiFi and Asus TUF Gaming B860M-Plus WiFi have identical storage capabilities. Both motherboards support RAID 0, RAID 1, RAID 5, and RAID 10 (1+0). Neither board supports RAID 0+1, which is consistent across both models.

There are no differences in the RAID support between the two motherboards, as they both offer the same options for RAID configurations.

In summary, the storage specifications of the B860-Plus WiFi and the B860M-Plus WiFi are the same, with both supporting the same set of RAID levels and excluding RAID 0+1.
