Socket and chipset
The ASRock B860M Challenger WiFi White is an ATX motherboard built around the Intel B860 chipset and LGA 1851 socket. It supports Intel Core Ultra Processors (Series 2) in a standard desktop form factor.
PCIe Gen5 M.2 upgrade
The board adds a CPU-attached M.2 slot running at PCIe 5.0 x4 (128 Gb/s) alongside two chipset Gen4 x4 slots. The jump is worth it when a Gen5 NVMe drive is the primary boot or scratch device.
White-themed ATX builds
The white PCB and heatsinks suit colour-coordinated ATX cases with room for four DDR5 DIMMs and a single x16 graphics card. Builders needing more than three M.2 slots or a smaller footprint should look elsewhere.

Questions about this item
What case clearance is needed for the 12.0-in x 9.6-in ATX board?
The board follows the standard ATX form factor at 12.0-in by 9.6-in, so any case that supports ATX will have the correct mounting holes and I/O shield cutout.
Which CPU power connectors must be seated for the 10+1+1+1+1 Dr.MOS phases to function?
Connect both the 24-pin ATX and the 8-pin EPS cables; missing the EPS connector leaves the VCore+GT+SA rails unpowered and the system will not POST.
Which M.2 slot should hold the OS drive for PCIe 5.0 x4 speed?
Install the boot NVMe SSD in the CPU-linked M2_1 Blazing M.2 socket, which runs at PCIe Gen5x4 (128 Gb/s), while M2_2 and M2_3 are chipset Gen4x4 (64 Gb/s).
