ASUS PRIME B860M-A-CSM Performance Meets Precision for Future-Ready Builds

High-End Performance Engineered for Professionals and Enthusiasts

The ASUS PRIME B860M-A-CSM is a powerhouse micro-ATX motherboard designed to fully harness the capabilities of Intel® Core™ Ultra Processors (Series 2) with the B860 chipset. With a 7+1+1+1 80A DrMOS power stage configuration and support for blazing-fast DDR5 memory up to 8666+ MT/s (OC), this board ensures exceptional processing stability and high-speed multitasking. The inclusion of PCIe 5.0 and dual ultra-fast M.2 slots—one supporting PCIe 5.0—means it’s built to handle next-gen GPUs and storage without compromise.

Built-In IT Management and Cooling Intelligence

Thanks to the ASUS Corporate Stable Model (CSM) program, the B860M-A-CSM includes ASUS Control Center Express—a robust IT management software that simplifies monitoring, maintenance, and deployment across networks. Its six-layer PCB layout enhances thermal performance and overclocking headroom, while onboard hybrid fan headers and ASUS Fan Xpert 2+ offer precise thermal control. Compatibility with ASUS AIO coolers ensures peak cooling under load, making it perfect for creators and professionals seeking reliability and efficiency.

DIY-Friendly Features and Immersive Connectivity

Engineered with DIY builders in mind, the board includes features like a pre-mounted I/O shield, Q-LED Core for POST diagnostics, SafeSlot PCIe reinforcement, and ProCool connectors for PSU durability. Aura Sync and Addressable Gen2 headers offer expansive RGB control, and its extensive USB lineup—including rear 20Gbps USB-C and front-panel 10Gbps USB-C—ensures rapid peripheral access. Whether you’re building for productivity, entertainment, or AI applications, this motherboard offers the flexibility and performance to scale with your needs.
