Overview

A Micro-ATX motherboard built on the Intel H810 chipset for LGA 1851 processors. It fits office builds and casual gaming systems that need PCIe 4.0 graphics and storage.

Board Layout and Cooling

The Micro-ATX PCB measures 244 by 222 mm and includes a backplate, VRM heatsinks, and an M.2 heatsink. Three 4-pin PWM headers handle CPU, chassis, and radiator fans. Digital RGB headers support addressable lighting strips.

Memory and Expansion

Two DIMM slots accept CUDIMM or UDIMM DDR5 modules up to 96 GB total with Intel XMP profiles up to 6400 MT/s. A single PCIe 4.0 x16 slot carries the graphics card, while a PCIe 4.0 x1 slot adds extra expansion.

Storage Connectivity

One M.2 slot runs at PCIe 4.0 x4 and the second at PCIe 4.0 x2, both supporting standard drives. Four SATA 6 Gbps ports provide additional capacity for hard drives or SATA SSDs.

Rear and Internal I/O

External ports comprise HDMI, DisplayPort, two USB 3.1 Type-A, four USB 2.0 Type-A, and a 1 GbE LAN jack. Internal headers include one USB 3.2 Gen 1 Type-C, one USB 3.0 header for two ports, one USB 2.0 header for two ports, front audio, SPI TPM, and three digital RGB connectors.
