ASUS PRIME H810M-A-CSM LGA1851 Micro-ATX Motherboard
The ASUS PRIME H810M-A-CSM is a micro-ATX motherboard built for DIY PC builders upgrading to Intel Core Ultra Processors (Series 2). It combines stable power delivery, modern storage connectivity, and AI-ready features in a compact form factor.
Why this product
6+1+1+1 power phase for stable delivery
Discrete MOSFETs and Digi+ voltage regulation ensure reliable power to the latest Intel processors during everyday use and light overclocking.
PCIe 4.0 M.2 slots up to 64Gbps
Two M.2 slots support fast NVMe SSDs—one at full PCIe 4.0 x4 speed and one at x2—for quick boot and app loading.
USB 10Gbps rear ports and 5Gbps Type-C
High-speed USB connectivity at the back and a front USB Type-C connector handle modern peripherals and external drives without bottlenecks.
AI PC-ready design
Built with the power and connectivity to support demanding AI applications on future Intel platforms.
Three Aura Sync RGB headers
All three addressable Gen 2 RGB headers work with ASUS Aura Sync for coordinated case lighting.

- Supports Intel Core Ultra Processors (Series 2) with LGA 1851 socket only—not compatible with older Intel or AMD platforms.
- Accepts DDR5 memory up to 6400MT/s in two DIMM slots (maximum 128GB total).
- Fits micro-ATX cases measuring at least 24.4 cm × 22.2 cm; will not fit mini-ITX or full-size ATX enclosures.
- Requires an 8-pin 12V CPU power connector and 24-pin main power connector from a standard ATX power supply.
- Supports Windows 11 (22H2 or later) and Windows 10 64-bit (21H2 or later); older versions are not compatible.
Best for
- First-time or budget-conscious PC builders stepping up to Core Ultra Series 2 without overpaying for features they won't use.
- System integrators and small businesses building stable, reliable commercial machines (ASUS Corporate Stable Model program).
- Builders who want fast NVMe storage and modern USB connectivity in a compact, space-saving form factor.
- Users planning mild overclocking or AI application work who need solid power delivery and sufficient M.2 slots.
Trade-offs
- Extreme overclockers — the 6+1+1+1 power phase is robust for stock and moderate tuning, but does not match high-end boards designed for sustained voltage pushing.
- Users with only DDR4 memory — this board has no DDR4 slots and will not accept older memory standard.
- Builders needing Thunderbolt or WiFi — it lacks both; only Intel 1Gb Ethernet and standard USB are provided.
- Full-size ATX builds — the micro-ATX layout suits compact cases but wastes space in larger chassis and may limit future expansion slots.
