  • Centralised control through AI Suite 3
  • Enhanced integrated graphics performance with GPU Boost
  • All-round energy efficiency and detailed CPU wattage control via EPU

LGA 1150 Micro-ATX motherboard

The ASUS H81M-K is a Micro-ATX board built around the Intel H81 chipset and the LGA 1150 socket. It targets builders assembling a compact office or home system with a fourth-generation Core processor. The layout provides one PCIe x16 slot and two PCIe 2.0 x1 slots for essential add-in cards.

Buyers needing a basic platform for integrated

This board suits users who rely on the processor’s integrated graphics and want the simplified setup of UEFI BIOS plus AI Suite 3 for system tuning. EPU energy controls help keep power draw low. Builders who require multiple high-speed storage connectors, additional PCIe x16 lanes or newer USB standards should look at a different platform.

Single PCIe x16 expansion slot

The only full-length slot is a single PCIe x16 connection, so the system can accommodate one graphics card or other x16 device. Two PCIe 2.0 x1 slots remain for supplementary cards such as sound or networking. If a build demands more than one x16 device, this motherboard cannot meet that requirement.

Questions about this item

Which ASUS H81M-K version should I choose for my LGA 1150 build?

This board is offered in a single Micro-ATX layout with the H81 chipset and LGA 1150 socket, so there are no alternative versions or capacities to compare.

What does the 170% USB 3.0 Boost figure mean once the board is installed?

It indicates that UASP-supported USB 3.0 devices can transfer data up to 170% faster than they would on a standard USB 3.0 implementation.

How does the PCIe 2.0 x16 slot limit graphics-card performance in practice?

The slot runs at PCIe 2.0 speeds, so modern GPUs will operate at half the bandwidth of a PCIe 3.0 or 4.0 link, which can cap peak throughput on high-end cards.
