ASUS Pro Q870M-C-CSM LGA1851 Micro-ATX Motherboard
The ASUS Pro Q870M-C-CSM is a micro-ATX business motherboard built for enterprises and system integrators who need stability, security, and long-term supply guarantees. It combines Intel's latest Core Ultra Processors (Series 2) with ASUS's CSM program for predictable lifecycle support and integrated management tools.
Why this product
Intel vPro and TPM security
Self-recovering BIOS, onboard TPM, and NIST SP 800-193 compliance protect against firmware tampering and unauthorized access. ASUS Control Center Express simplifies enterprise-level monitoring and administration across multiple systems.
CSM program ensures supply stability
ASUS's Commercial System Maintenance program guarantees stable motherboard availability, end-of-life notifications, and IT software support designed for business deployments that cannot tolerate unexpected discontinuation.
PCIe 5.0 and DDR5 for current hardware
One PCIe 5.0 x16 slot and up to 256GB of DDR5 memory support demanding workloads and peripherals without architectural bottlenecks.
Built for 24/7 operation
Tested under 45°C temperature and 80% humidity with stainless-steel corrosion-resistant back panel and overvoltage protection to survive continuous industrial use.
Diagnostic and troubleshooting tools
Q-LED Core status display, COM debug header, and box headers streamline system assembly and reduce mean-time-to-repair in data centre environments.

Best for
- Business deployments with predictable lifecycle requirements
- System integrators managing fleets of workstations or thin clients
- Environments requiring 24/7 uptime and enterprise security compliance
- Compact builds that still need fast NVMe and PCIe 5.0 support
- Data centres or server rooms where corrosion resistance and industrial durability matter
Trade-offs
- Consumer or enthusiast builds: No overclocking support and no integrated Wi-Fi or Bluetooth for mainstream use cases.
- High-end gaming or content creation: Single 1Gb Ethernet and entry-level Realtek audio codec lack the bandwidth or fidelity of workstation-class boards.
- Budget-conscious buyers: CSM program support and enterprise-grade components command a premium over consumer micro-ATX alternatives.
- Wireless-first workflows: No onboard Wi-Fi or Bluetooth; optional M.2 E Key module required for wireless capability.
