Product information

Description

The ASUS PRIME B860M-A-CSM is a micro ATX motherboard built around the Intel B860 chipset and LGA 1851 socket, designed to support Intel Core Ultra processors (Series 2). It offers four DDR5 DIMM slots supporting up to 256 GB of memory, multiple storage interfaces including M.2 and SATA III, RAID support for levels 0, 1, 5 and 10, and a 2.5 Gigabit Ethernet port for high-speed networking. The board features a robust power design and integrated cooling provisions to maintain stable operation under load, and provides firmware and software tools for system tuning and management.

Advantages

The PRIME B860M-A-CSM combines compact micro ATX sizing with a modern LGA 1851 socket and Intel B860 chipset, enabling use of the latest Intel Core Ultra processors (Series 2). Support for DDR5 memory up to 256 GB and multiple storage options (M.2 and SATA III) allows flexible system configurations. Built-in RAID support and a 2.5 GbE interface meet needs for fast storage arrays and network throughput, while onboard power delivery and cooling features improve stability for sustained workloads. Firmware and software utilities simplify tuning and system management for both end users and IT administrators.

Suitable for

  • Compact desktop builds using Intel Core Ultra processors (Series 2)
  • Office and business PCs requiring stable networking and manageability
  • Home or small-office systems needing multiple storage devices and RAID
  • General-purpose PCs where DDR5 performance and upgradeability are desired
