ASRock B860M Challenger WiFi Intel motherboard

LGA 1851 Intel B860 Micro ATX motherboard

The ASRock B860M Challenger WiFi is built for Intel Core Ultra Series 2 processors on the LGA 1851 socket. It uses the Intel B860 chipset and provides onboard Intel Xe LPG graphics. The board supports up to 256 GB of DDR5 5600 memory across four 288 pin slots running in dual channel mode with Intel XMP 3.0 profiles. It is aimed at builders who want a compact platform for modern Intel CPUs.

Straightforward installation

The board follows the Micro ATX form factor so it fits most cases designed for that size. CPU power uses a 10+1+1+1+1 phase Dr.MOS design that connects with regular EPS cables. Four DDR5 slots are spaced normally and the single PCI Express 5.0 x16 slot sits in the top position. Common issues include forgetting to seat the 288 pin DDR5 modules fully until the latches click and overlooking the extra 4 pin CPU power connector needed for full phase operation.

Suits compact Core Ultra builds needing 2.5 Gbps

This motherboard fits users building a smaller system with an Intel Core Ultra Series 2 processor who need 2.5 Gbps wired networking and wireless connectivity. The four SATA 6Gb/s ports and three M.2 sockets cover typical storage needs. Builders requiring more than one full length PCIe 5.0 x16 slot or specialised server features such as ECC memory should look at larger chipset options instead.
