This article covers MSI PRO H810M-B マザーボード mATX.

Overview

The MSI PRO H810M-B is a microATX motherboard built around the Intel H810 chipset, designed for the latest Intel Core Ultra (Series 2) processors on the LGA1851 socket. It brings together DDR5 memory support (up to 6400 MT/s), a PCIe 5.0 x16 slot, and an M.2 Gen4 slot, offering a balanced feature set for business and productivity builds. This board targets office PCs and budget-conscious builders who need a stable, reliable platform without paying for gaming-oriented extras like overclocking or multiple PCIe slots. A direct 6-phase (P-PAK) VRM with FROZR Guard cooling ensures clean power delivery and thermal stability during long work sessions. Connectivity includes Realtek 2.5G LAN for fast wired networking, USB 5Gbps Type-A ports on the rear I/O, 7.1-channel HD audio, and display outputs supporting 4K at 60Hz. It covers all the essentials for a modern business desktop without unnecessary frills.

Compatibility Guide

CPU Socket: LGA1851, exclusively for Intel Core Ultra (Series 2) processors. LGA1700 CPUs (12th to 14th Gen Core) are physically incompatible. Memory: 2 x DDR5 DIMM slots, dual-channel, up to 6400 MT/s (1DPC 1R). DDR4 is not supported. Form Factor: microATX (244mm x 211mm). Fits most mATX cases, but check internal clearance for the board width. Expansion Slots: 1 x PCIe 5.0 x16 (Steel Armor reinforced). Backward compatible with PCIe 4.0/3.0 graphics cards. Storage: 1 x M.2 Gen4 x4 slot (64 Gbps) + 4 x SATA 6Gbps ports. Mix NVMe and SATA SSDs freely. Power: 1 x 8-pin EPS CPU power connector. A 500W–650W PSU is sufficient for typical office builds with a discrete GPU.

Product Info

The MSI PRO H810M-B sits in the entry-to-mid-range segment, offering the latest platform features at a budget-friendly price. It launched in the second half of 2025, with an estimated street price between ¥18,000 and ¥25,000 before tax. MSI provides a standard 3-year warranty.

Best Use Cases

Office PC / Business Workstation Builders: The combination of Intel Core Ultra processing power and fast DDR5 memory handles spreadsheets, document editing, video conferencing, and multitasking with ease. The 2.5G LAN port is a bonus for remote work or large file transfers. Budget-Conscious Early Adopters: If you want to experience the LGA1851 platform and PCIe 5.0 without spending on a Z-series board, the H810M-B is a solid choice. You get the key modern interfaces at a lower cost. Compact / Quiet PC Enthusiasts: With limited expansion, this board runs cool and fits easily into small mATX cases, making it ideal for a low-noise, low-heat build. Not for Gamers or Creators: The single M.2 slot and only two memory DIMMs limit upgrade headroom. For gaming or content creation, consider a B860 or Z890 board with more slots and overclocking support.

Things to Consider

Only 2 DIMM Slots: Maximum memory capacity is 64 GB (2 x 32 GB). If you anticipate needing more than 64 GB, look for a board with four slots. Single M.2 Slot: You get one Gen4 NVMe slot. Additional storage must use SATA SSDs, which are slower. For multiple fast SSDs, choose a motherboard with two or more M.2 slots. Chipset Limitations: H810 offers fewer PCIe lanes than B860 or Z890. Running multiple PCIe expansion cards simultaneously may be constrained. No Overclocking: CPU and memory overclocking are not supported. This board is designed for stock operation only. * Competition: Similar boards like the ASUS PRIME H810M-A and GIGABYTE H810M S2H offer comparable specs. Compare BIOS features, warranty terms, and I/O layout before buying. ## FAQ
Q: Can I use an Intel Core i5-14600K (LGA1700) with this motherboard? A: No. The PRO H810M-B is LGA1851-only and supports only Intel Core Ultra (Series 2) processors. LGA1700 CPUs are physically incompatible. Q: Will a PCIe 5.0 graphics card run at full speed in this board? A: Yes. The single PCIe 5.0 x16 slot provides full bandwidth for PCIe 5.0 GPUs like the GeForce RTX 50 series or Radeon RX 9000 series. However, overall performance depends on the CPU and memory configuration. Q: Can I use DDR5-6800 or faster memory? A: Officially, the board supports up to 6400 MT/s (1DPC 1R). Faster memory may not run at its rated speed and could default to 6400 MT/s or fail to boot. Since overclocking is not supported, XMP/EXPO profiles will not work.
