Micro-ATX LGA 1150 Intel Motherboard

The ASUS H81M-K is a Micro-ATX board built for the LGA 1150 socket. It suits budget office builds or basic home PCs that need a compact layout. The H81 chipset provides essential I/O without overclocking features. It fits standard micro-ATX cases and power supplies.

UEFI BIOS with AI Suite 3 and EPU

A new UEFI BIOS replaces the legacy interface with mouse-friendly menus and clearer hardware information. AI Suite 3 bundles monitoring, fan control and power-saving profiles into one desktop utility. The EPU engine adjusts CPU wattage dynamically to lower idle consumption. USB 3.0 Boost adds UASP support for 170% faster transfer speeds than traditional USB 3.0.

Expansion capacity and graphics headroom

One PCIe x16 slot accepts a single discrete graphics card for gaming or multi-monitor work. Two PCIe 2.0 x1 slots handle add-in cards such as sound, networking or extra USB ports. Integrated graphics from the processor cover everyday video and light 2D tasks. The board lacks a second x16 slot, so multi-GPU configurations are not possible.

Questions about this item

Will the LGA 1150 socket or H81 chipset need replacement during the board's life?

The LGA 1150 socket is fixed to the PCB and the H81 chipset is soldered; neither is designed for user replacement, so the board itself would be swapped if either fails.

What limit appears first when the PCIe 2.0 x16 slot runs at full load for hours?

The PCIe 2.0 x16 link caps GPU bandwidth at 8 GT/s per lane, so sustained heavy compute or mining workloads hit that ceiling before the board's power phases do.

How loud and hot does the board get when the EPU feature manages CPU wattage all day?

With no active chipset fan and EPU power management active, the H81M-K runs passively cooled and only warm during continuous operation.
