It appears that PCEkspert managed to leak some photos of the ASUS ROG Strix B860-A Gaming WiFi Motherboard ahead of launch.
Taken from TPU … Ahead of their January 2025 launch, Socket LGA1851 motherboards based on Intel’s mid-range B860 chipset are making their way to retailers. One such board was snapped by Polish tech site PCEkspert. The ASUS ROG Strix B860-A Gaming WiFi, as with all Strix-A branded motherboards in the past two generations, comes with a white PCB, and white or silver/chrome components, with some contrasting black bits.
The Intel B860 chipset, in all likelihood, is differentiated from the Z890 by a lack of CPU overclocking support, while retaining memory overclocking capabilities; fewer downstream PCIe lanes, and a narrower 4-lane DMI 4.0 chipset bus, compared to the 8 lanes of the Z890 and H870. The box art reveals that the board features a 14-phase CPU VRM, one M.2 NVMe Gen 5 slot wired to the CPU that doesn’t eat into the x16 PEG, and at least three additional M.2 Gen 4 NVMe slots, two of which come from the PCH, and the third one from the CPU. Networking includes a 2.5 GbE and Wi-Fi 7 wireless networking, while the onboard audio solution could feature at least a mid-range codec such as the ALC1200 or ALC4080.
