Best for
- Compact builds and smaller cases needing full-featured LGA1851 support
- DDR5-first builders who want high memory speeds (up to 7200MT/s) without overcomplication
- DIY PC builders seeking straightforward UEFI BIOS controls and intuitive Fan Xpert 2+ management
- Systems intended for AI workloads, with Intel Core Ultra Series 2 optimization built in
- Users needing fast storage via PCIe 4.0 NVMe and graphics expansion without complexity
Trade-offs
- Full-size ATX builds. Micro-ATX form factor limits expansion slot count to 1 PCIe x1 and may not fit standard ATX cases.
- Demanding storage arrays. Only 1 M.2 slot and 4 SATA ports; systems needing more simultaneous drives should consider larger boards.
- Extreme overclocking or advanced silicon lottery tuning. H810 chipset with fixed power phases suits stable performance over maximum frequency tweaking.
- AMD Ryzen or older Intel socket users. LGA1851 support is exclusive to Intel Core Ultra Series 2; no backward compatibility.
- Multi-GPU setups. Single PCIe x16 slot and one PCIe x1 slot limit parallel GPU installations.

Digital Power Design
Stable power is crucial for maximizing the performance of Intel® Core™ Ultra Processors (Series 2). The PRIME H810M-K features an 6+1+1+1 phase design with discrete MOSFETs, ensuring efficient and stable power delivery for Intel® processors plus steady performance for day-to-day use.
Cooler by design
The PRIME H810M-K motherboard is engineered with onboard chipset heatsink and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads. Each onboard header supports auto-detection of PWM or DC fans.
Empowering connections
Numerous USB ports support high-end rigs loaded with peripherals, including two rear USB Type-A ports with transmission speeds of up to 5Gbps and a front USB Type-C® connector with ultrafast USB 5Gbps for transmission speeds of up to 5Gbps.
Realtek 1 Gb Ethernet
Realtek Ethernet reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfer.
DIY friendly
SafeSlot Core+ is a one-piece stainless-steel brace that shields the slot to protect it from damage. The metal cover is tightly secured to the slot with hooks, and the entire assembly is firmly anchored to the PCB with strengthened solder points to provide a secure foundation for heavyweight graphics cards.
UEFI BIOS
The renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.
Aura Sync
