Intel Core Ultra Series 2 Ready

The ASUS PRIME B860-PLUS WIFI-CSM is an ATX motherboard built for the LGA 1851 socket and Intel B860 chipset. It supports Intel Core Ultra Processors (Series 2) with a 8+1+1+1 80A DrMOS power design and ProCool connector. Four DDR5 slots accept up to 256GB at speeds up to 8200+ MT/s via XMP 3.0. Connectivity includes WiFi 6E, Bluetooth 5.3 and 2.5Gb Ethernet.

Compatibility Checklist

Verify that your CPU is an Intel Core Ultra Series 2 processor for the LGA 1851 socket. Ensure the chassis fits an ATX board and that the power supply provides an 8-pin EPS connector. Confirm DDR5 modules are on the vendor QVL for 8200+ MT/s operation. Check case front-panel headers for a USB 5Gbps Type-C connector and allow space for the M.2 heatsink on the primary slot.

Business Builders and AI Workstations

IT managers gain ASUS Control Center Express for remote monitoring and CSM programme stability with end-of-life notices. Creators and AI developers benefit from PCIe 5.0 x16, a PCIe 5.0 M.2 slot, USB 20Gbps Type-C and quad-channel 7.1 audio. Budget gamers or legacy peripheral users lacking DDR5 or LGA 1851 CPUs should consider alternative platforms.

Questions about this item

What comes in the box with the ASUS PRIME B860-PLUS WIFI-CSM and do I need to buy a Wi-Fi antenna separately?

The motherboard ships with a rear Wi-Fi module included, so no separate antenna purchase is required for the on-board WiFi 6E and Bluetooth 5.3 connectivity.

Should I choose the PCIe 5.0 M.2 slot or the PCIe 4.0 M.2 slot for my primary OS drive?

Use the M.2_1 slot (Key M, type 2242/2260/2280) which supports PCIe 5.0 x4 mode for the fastest boot and application load times; the M.2_2 slot runs at PCIe 4.0 x4 and also accepts 22110-length drives.

What does the 8200+ MT/s DDR5 memory rating mean once the board is built into a working PC?

It indicates the maximum overclocked data rate supported via Intel XMP 3.0 profiles on the four 288-pin slots; actual speed depends on the memory kit and CPU memory controller, with dual-channel operation up to 256 GB total capacity.
