ASUS Prime B860M-A-CSM LGA1851 DDR5 MicroATX Motherboard

ASUS PRIME series motherboards are expertly engineered to unleash the full potential of the latest Intel Core Ultra processors (Series 2). Boasting a robust power design, comprehensive cooling solutions, and intelligent tuning options, the PRIME B860M-A-CSM motherboard provides everyday users and PC DIY builders with a range of performance optimizations via intuitive software and firmware features. Designed to be Advanced AI PC-ready, it delivers the power and connectivity required for demanding AI applications.

Robust Power Design
Stable power is crucial for maximizing the performance of Intel Core Ultra processors (Series 2). The PRIME B860M-A-CSM is built to meet the demands of high-core-count CPUs. It features 7(80A) + 1(80A) + 1(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amps each. This configuration delivers 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 empowers users to achieve unmatched memory performance with cutting-edge CUDIMM memory. Through a comprehensive two-stage 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 cutting-edge DDR5-7600 speeds or higher.

Cooling
The PRIME B860M-A-CSM motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under heavy workloads.

USB 20Gbps Port
A wide array of USB ports supports high-end peripherals, including a rear-panel USB Type-C ® port delivering data transfer speeds of up to 20Gbps.

PCIe 5.0
The latest processors introduce PCIe 5.0 support, which doubles data transfer speeds compared to PCIe 4.0, improves signal integrity, and provides backward-compatible CEM connectors along with support for previous PCIe versions.
