ASRock B860M Lightning WiFi VS ASRock B860M Pro-A

Both the ASRock B860M Lightning WiFi and the ASRock B860M Pro-A share a common foundation: the LGA 1851 socket with a B860 chipset, a Micro-ATX form factor at identical 244 × 244 mm dimensions, and the same 3-year warranty. Both boards also support overclocking and feature dual BIOS, which provides a valuable safety net for failed BIOS updates. Neither board integrates a CPU or graphics solution, and both offer HDMI 2.1 output for connecting a display directly — useful when pairing with a processor that has integrated graphics.

The decisive differentiator in this group is connectivity. The Lightning WiFi includes built-in Wi-Fi and Bluetooth, while the Pro-A offers neither. In practice, this means the Pro-A requires a separate PCIe or USB wireless adapter to achieve wireless networking, adding cost and consuming an expansion slot or USB port. For a compact Micro-ATX build where slot real estate is limited, having wireless built in is a genuine convenience advantage. The Lightning WiFi also adds RGB lighting, which the Pro-A omits — a cosmetic difference, but relevant for users building inside a windowed case.

The Lightning WiFi holds a clear edge in this group. The integrated Wi-Fi and Bluetooth alone justify the distinction for anyone targeting a cable-free setup, and the dual BIOS safety feature is equally present on both boards. The Pro-A is not deficient in its core platform specs, but it offers strictly less out of the box when it comes to general feature set.

Both the ASRock B860M Lightning WiFi and ASRock B860M Pro-A share identical memory specifications. Each motherboard supports a maximum memory amount of 256GB, with a maximum RAM speed of 5600 MHz. Additionally, both models can handle overclocked RAM speeds of up to 8666 MHz. They are equipped with 4 memory slots, which allows for a significant amount of RAM expansion. Both motherboards also support DDR5 memory and operate with a dual memory channel configuration. Furthermore, neither motherboard supports ECC (Error-Correcting Code) memory.

Given that all these key memory specs match across both products, users can expect the same memory performance and expansion options from either motherboard.

In summary, there is no difference between the ASRock B860M Lightning WiFi and ASRock B860M Pro-A when it comes to memory support and features. Both offer identical capabilities in this category.

The ASRock B860M Lightning WiFi and ASRock B860M Pro-A differ in their port offerings. The Lightning WiFi model provides more USB ports, including 2 USB 3.2 Gen 2 (USB-A) ports and 4 USB 3.2 Gen 1 (USB-A) ports, compared to the Pro-A’s 3 USB 3.2 Gen 1 (USB-A) ports. The Lightning WiFi also includes a USB 4 40Gbps port, a feature not present on the Pro-A. Additionally, the Lightning WiFi model supports Thunderbolt 4, while the Pro-A lacks any Thunderbolt ports.

Both motherboards include the same number of USB 2.0 ports (2), DisplayPort outputs (1), HDMI outputs, and RJ45 ports (1), making them comparable in these aspects. The Pro-A, however, features a USB 3.2 Gen 2x2 port, which the Lightning WiFi does not have.

In summary, while both motherboards offer a solid selection of ports, the ASRock B860M Lightning WiFi has a more comprehensive set, including USB 4, Thunderbolt 4, and additional USB 3.2 Gen 2 ports, whereas the Pro-A has a USB 3.2 Gen 2x2 port that the Lightning WiFi lacks.

The ASRock B860M Lightning WiFi and ASRock B860M Pro-A are similar in several connector-related features but differ in a few key areas. Both models have 2 USB 3.2 Gen 1 ports and 4 USB 2.0 ports through expansion. They also both offer 4 SATA 3 connectors, 2 USB 3.0 ports through expansion, and no SATA 2 connectors. Each motherboard includes a TPM connector and lacks an mSATA connector or U.2 sockets.

One difference between the two is in the number of fan headers: the Lightning WiFi model has 7 fan headers, while the Pro-A has 6. Additionally, the Lightning WiFi model has 4 M.2 sockets, one more than the Pro-A's 3.

In summary, while both motherboards provide a solid selection of connectors, the ASRock B860M Lightning WiFi offers more fan headers and M.2 sockets, whereas the ASRock B860M Pro-A offers fewer fan headers and M.2 sockets.

The ASRock B860M Lightning WiFi and ASRock B860M Pro-A both feature a PCIe 5.0 x16 slot, but the configurations of their expansion slots differ. The Lightning WiFi has no PCIe 4.0 x16 slots, PCIe 3.0 x16 slots, PCIe x1 slots, or PCI slots, and it lacks both PCIe x4 and PCIe x8 slots. In contrast, the Pro-A includes a PCIe x4 slot, but like the Lightning WiFi, it also lacks PCIe 4.0 x16, PCIe 3.0 x16, PCIe x1, and PCI slots.

In terms of other expansion slots, both models feature only a PCIe 5.0 x16 slot, with the Pro-A being the only one to include a PCIe x4 slot.

Overall, both motherboards are similar in having a PCIe 5.0 x16 slot, but the ASRock B860M Pro-A offers an additional PCIe x4 slot, which the ASRock B860M Lightning WiFi does not have.

Both the ASRock B860M Lightning WiFi and ASRock B860M Pro-A feature 7.1 audio channels, ensuring high-quality sound output. However, they differ in the availability of additional audio features. The Lightning WiFi model includes an S/PDIF Out port, while the Pro-A does not. In terms of audio connectors, the Lightning WiFi has 2 connectors, while the Pro-A has 3, offering slightly more flexibility in connecting audio devices.

In summary, both motherboards support 7.1 audio channels, but the ASRock B860M Lightning WiFi has an S/PDIF Out port, while the ASRock B860M Pro-A has one more audio connector.

Both the ASRock B860M Lightning WiFi and ASRock B860M Pro-A support the same RAID configurations. These include RAID 1, RAID 10 (1+0), RAID 5, and RAID 0. Neither motherboard supports RAID 0+1, which is not available on either model.

Overall, the storage capabilities in terms of RAID support are identical for both motherboards, with no difference between the ASRock B860M Lightning WiFi and the ASRock B860M Pro-A in this regard.
