ASUS B860M-BRO Intel B860 (LGA1851) mATX motherboard

SKU CH-QZT0-35ZPQ

mATX board for LGA1851 CPUs with dual DDR5 slots up to 128 GB, 8800 MT/s OC, PCIe 4.0, 2.5 Gb Ethernet, rear USB 10 Gbps Type-A and front USB 5 Gbps Type-C

  • Supports 2nd Gen Intel Core Ultra CPUs via LGA1851 socket
  • Up to 128GB DDR5 memory with 8800+ MT/s overclocking potential
  • PCIe 4.0 lanes for high-speed storage and expansion cards
  • Realtek 2.5Gb Ethernet delivers fast wired network connectivity
  • Rear USB 10Gbps Type-A plus front USB 5Gbps Type-C for versatile I/O

Optimised for Intel Core Ultra Series 2

This mATX motherboard uses the Intel B860 chipset and LGA1851 socket to support second-generation Intel Core Ultra processors. It targets builders who want a compact foundation for modern AI-ready workloads and high-speed memory without a full-size ATX layout.

Dual M.2 slots and front USB 5Gbps Type-C®

Two M.2 sockets and a rear USB 10Gbps Type-A port provide fast storage and peripheral bandwidth. The front-panel USB 5Gbps Type-C® header simplifies case connectivity, while Realtek 2.5Gb Ethernet, HDMI, VGA and SATA 6 Gbps cover display and networking needs.

Check DDR5 clearance and CPU cooler height

Verify that your memory modules fit the two DDR5 slots and that your chosen cooler clears the power delivery heatsinks in a micro-ATX chassis. Builders needing more than two DIMM slots, additional M.2 drives or legacy PCI slots should consider a larger form factor.

Questions about this item

Will the DDR5 slots need any firmware updates to keep running at 8800 MT/s over time?

The board supports ASUS Enhanced Memory Profile III so XMP or AEMP profiles can be re-applied after any BIOS update; no separate slot maintenance is required.

What thermal limit appears first when the VRM runs flat-out on a 2nd Gen Core Ultra?

Comprehensive thermal management with integrated cooling solutions is designed to maintain optimal temperatures during sustained workloads.

How loud or hot does the board get when the 2.5Gb Ethernet and rear USB 10Gbps ports are active all day?

Advanced power architecture delivers stable energy efficiency while comprehensive thermal management keeps temperatures in check for uninterrupted operation.
