ASUS Pro Q870I-C-CSM Mini-ITX Q870 Business Motherboard
The ASUS Pro Q870I-C-CSM is a Mini-ITX business motherboard built for AI-ready workstations and enterprise deployments. It combines Intel Core Ultra (Series 2) support with PCIe 5.0 connectivity, DDR5 memory, and integrated IT management tools designed for organisations that need secure, remote-manageable systems.
Why this product
Intel Core Ultra Series 2 ready
LGA1851 socket supports the latest Intel Core Ultra processors with up to 65W TDP, enabling advanced AI computing on compact form factors.
PCIe 5.0 and DDR5 connectivity
One PCIe 5.0 x16 SafeSlot for graphics or expansion, plus DDR5 SO-DIMM slots supporting up to 6400 MT/s and 128GB total capacity.
Built-in IT management
ASUS Control Center Express provides remote monitoring and administration; ASUS CSM program ensures stable supply and end-of-life support.
Enterprise security features
Intel vPro support, TPM onboard, ASUS Boot Defender, and Intel TXT enable hardware-level security and compliance for business environments.
Dual USB 10Gbps Type-C ports
Rear and front 10Gbps USB Type-C connectors plus three additional 10Gbps Type-A ports for high-speed data and peripheral connectivity.
- SocketIntel LGA1851
- ChipsetIntel Q870
- Form FactorMini-ITX (6.7 × 6.7 inches)
- Memory slots2 × DDR5 SO-DIMM (up to 128GB, up to 6400 MT/s)
- PCIe Expansion1 × PCIe 5.0 x16 SafeSlot
- Storage1 × M.2 PCIe 5.0 x4, 2 × SATA 6Gb/s
- SKUASU-2695
- EAN4711636208857
- Fits Intel Core Ultra Processors (Series 2) only — LGA1851 socket is not compatible with older Intel desktop or laptop CPUs.
- Mini-ITX form factor (6.7 × 6.7 inches) — requires a compact Mini-ITX case; will not fit in ATX or Micro-ATX chassis.
- Supports DDR5 SO-DIMM memory exclusively — standard DDR5 UDIMM modules are not compatible.
- Supports Windows 11 and Windows 10 64-bit operating systems only.
- Wi-Fi requires a separately purchased M.2 CNVi module (Key E, 2230 form factor); the board has the slot but no module is included.
Best for
- AI workstations and machine learning deployments
- Compact office and enterprise builds requiring managed IT oversight
- Systems needing secure remote access and hardware-level authentication
- Organisations prioritising long-term supply stability and vendor support
Trade-offs
- AMD processor builds: This board supports Intel only and cannot be used with Ryzen, EPYC or other AMD CPUs.
- Large-form-factor systems: Mini-ITX limits expansion to one 16x PCIe slot and two SATA ports; ATX motherboards offer more slots and storage options.
- Gaming or consumer overclocking: This is a locked business-class board; it lacks unlocked BIOS tuning and is designed for stability, not performance tweaking.
- Systems with standard DDR5 memory: This board requires DDR5 SO-DIMM modules (laptop-style); it cannot use standard desktop DDR5 UDIMMs.
- High-core-count workloads: CPU power is limited to 65W TDP; processors of this class are single-socket designs, not multi-socket or high-power chips.
