The MSI PRO H810M-E LGA1851 DDR5 mATX Motherboard pairs Intel Core Ultra Processors (Series 2) with a full-speed PCIe 5.0 x16 expansion slot and 2.5Gbps wired networking on a compact micro-ATX PCB. Measuring 220 mm by 243.84 mm, it offers a space-efficient foundation for desktop deployments without sacrificing modern interface standards.

Built for essential business and workstation builds

Designed around the Intel H810 chipset and LGA 1851 socket, this micro-ATX board provides native support for Intel Core Ultra Processors (Series 2). Main power is supplied via a standard 24-pin ATX and 8-pin ATX 12V power connector layout, ensuring straightforward integration with standard desktop power supplies. Internal thermal management is managed through one CPU fan header and two system fan headers to maintain consistent airflow across the chassis. For lighting customisation, the PCB provides three Addressable V2 RGB LED connectors (JARGB_V2).

PCIe 5.0 bandwidth for modern GPUs

Despite its micro-ATX footprint, the motherboard includes a primary PCIe 5.0 x16 slot for dedicated graphics cards. This interface provides double the throughput of PCIe 4.0, preserving full bandwidth availability for current and future GPU hardware. A secondary PCIe 4.0 x1 slot is located below the main graphics slot for auxiliary expansion cards.

DDR5 memory speed and high-speed NVMe support

The board features two DDR5 UDIMM slots in a dual-channel memory configuration, supporting up to 128 GB total system capacity. System builders can run memory at standard JEDEC frequencies starting from 4800 MT/s or activate profile clock speeds reaching up to 7200 MT/s (OC).

Storage options combine ultra-fast NVMe drive support with traditional SATA interfaces:

• 1x M.2 Slot: Runs over PCIe 4.0 x4 for quick OS boot times and fast application file access, accommodating both 2280 and 2260 form factor drives.
• 4x SATA 6Gb/s Ports: Provides four dedicated connection points for high-capacity 2.5-inch SSDs or 3.5-inch hard drives.

2.5Gb Ethernet, dual 4K display outputs, and front USB-C

Network performance is driven by an onboard Realtek 8125D controller delivering 2.5Gbps LAN speeds over copper Ethernet. This provides 2.5 times the transmission rate of standard Gigabit network adapters for quick local file transfers.

For systems using integrated processor graphics, the rear panel provides two digital display ports:

Peripheral expansion includes two USB 5Gbps Type-A ports and four USB 2.0 ports on the rear I/O. Front panel connectivity is handled via internal headers, providing one USB 5Gbps Type-C header, one USB 5Gbps Type-A header supporting two ports, and two USB 2.0 headers supporting four ports. Integrated 7.1-channel High Definition Audio is powered by the Realtek ALC897 codec. The motherboard supports Windows 11 64-bit operating systems.
