ASUS PRIME B860-PLUS WIFI CSM – Intel Core Ultra Series 2 Motherboard

About the ASUS PRIME B860-PLUS WIFI Motherboard

The ASUS PRIME B860-PLUS WIFI is built for Intel's Core Ultra Series 2 processors on the new LGA1851 socket. This B860 chipset board gives you modern platform features without the Z890 price tag. It's designed for mainstream PC builders who want WiFi 6E, DDR5 support, and PCIe 5.0 connectivity.

The ATX form factor fits standard cases. Four DIMM slots and solid VRM cooling make this board ready for serious builds.

What This ASUS PRIME B860-PLUS WIFI Does for You

Building a new Intel Core Ultra system means you need an LGA1851 motherboard. This board keeps things straightforward. WiFi 6E connectivity means you can skip buying a separate WiFi card and save that PCIe slot for something else.

Four M.2 slots (two M.2, four SATA) let you run multiple fast drives without cable clutter. The PCIe 5.0 x16 slot supports the latest graphics cards. DDR5 memory support up to 8666MT/s means your RAM won't bottleneck performance.

The Realtek 2.5Gb ethernet gives you wired speeds faster than standard gigabit. USB 20Gbps Type-C on the rear panel handles fast external drives.

Build Quality and Features

ASUS includes their 5X Protection III features—DIGI+ VRM with DrMOS, LANGuard, SafeSlot reinforcement, and overvoltage protection. The pre-mounted I/O shield saves you a step during installation. Q-LED diagnostic lights help troubleshoot if something goes wrong.

VRM heatsinks and M.2 heatsink keep components cool under load. The board supports ASUS Armoury Crate software for fan control and RGB lighting management.
