  • Storage interfaces: M.2, SATA III
  • Number of supported storage drives: 7
  • RAID support: 0, 1, 5, 10
  • Graphics: Parallel processing technology support

The ASUS PRIME B860-PLUS-CSM is ready for advanced AI PCs, offering the power and connectivity required for demanding AI applications.

ASUS Corporate Stable Model (CSM)

The Corporate Stable Model (CSM) from ASUS is a commercial program designed to provide stable and reliable motherboards. It offers up to 36 months of product lifecycle support and a 6-month end-of-life notice, so your organization has sufficient time to prepare for the product transition. Each purchase of an ASUS CSM motherboard comes with the ASUS Control Center Express - server-level IT management software.

Powerful Power Design

Stable power supply is critical for harnessing the full performance of Intel Core Ultra (Series 2). The Prime B860-Plus-CSM is designed to meet the needs of processors with a high core count. It features 8(80A) + 1(80A) + 1(80A) + 1(80A) power phases that integrate high and low side MOSFETs and drivers in packages rated for up to 80 amps each. This configuration ensures optimal power delivery, efficiency, stability, and performance for current and future Intel® processors.

AEMP III for Ultimate DDR5 Performance

ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that allows users to achieve unparalleled memory performance using advanced CUDIMM memory. Through a two-phase tuning process, AEMP III first optimizes the clock driver and then the memory frequency. This results in the best balance between performance and stability, even at top speeds of DDR5-7600 or higher.

DIMM Fit

DIMM Fit is an exclusive ASUS BIOS feature that accurately analyzes individual memory modules to optimize performance and identify potential issues. This offers maximum performance, compatibility, and system stability. Whether you are an overclocking user seeking ultimate performance, a competitor pursuing the most versatile gameplay, or a content creator prioritizing the utmost stability, DIMM Fit provides optimizations tailored to your needs and hardware configuration.

3x M.2 slots (up to 128Gbps)

The PRIME B860-PLUS-CSM offers a total of three M.2 slots, one of which supports data transfer speeds of up to 128Gbps via PCIe 5.0 and one 64Gbps via PCIe 4.0. This allows for faster boot and application load times with operating system or application drives.

ASUS Fan Xpert 2+

The ASUS Fan Xpert 2+ software provides full control over the fans. Auto-Tuning works intelligently and adjusts all parameters with a single click. There is also the Extreme Quiet mode, which reduces the speed of the case fans below the minimum preset value, keeping your system silent during light tasks. The fans can also be controlled through the UEFI BIOS.

PCI Express 5.0 x16 Support

The latest processors introduce support for PCIe 5.0, doubling data transfer speeds compared to PCIe 4.0, improving signal integrity, and providing backward-compatible CEM connections and support for previous PCIe versions.

UEFI BIOS

The UEFI environment offers user-friendly configuration options for novice PC users and advanced features for experienced users.

DIY Friendly

The PRIME B860-PLUS-CSM motherboard features EZ PC DIY innovations that simplify and speed up the process of building a computer, making DIY easy and convenient.

Pre-installed metal I/O shield

The pre-installed metal I/O shield protects the ports, simplifies the building process, enhances functionality, and improves aesthetics for PC DIY enthusiasts.
