H81M-P33 LGA 1150 Micro ATX Board

The MSI H81M-P33 is an Intel H81 chipset motherboard built for the LGA 1150 socket. It fits a Micro ATX form factor and supports DDR3 memory up to 16 GB capacity. The board targets cost-conscious builds using 4th generation Core i7, i5, i3, Pentium or Celeron processors.

Compatibility Check Before Ordering

Verify that your CPU uses the LGA 1150 package and is supported by the H81 chipset. Confirm your memory modules are DDR3 DIMMs rated for standard speeds up to 1600 MHz. Ensure the chassis accepts a Micro ATX board and provides a standard 24-pin ATX plus 4-pin CPU power connector.

Build Integration And Expansion

The board supplies one PCIe 3.0 x16 slot for a graphics card and one PCIe 2.0 x1 slot for add-in cards. Storage connects through two SATA 6 Gbps ports and four SATA 3 Gbps ports. Rear I/O includes four USB 2.0 ports, Gigabit Ethernet driven by a Realtek 8111 controller and 8-channel audio via the Realtek ALC887 codec.

Questions about this item

What comes in the box and what must I source separately?

The package contains the motherboard, a CMOS battery, one SATA cable and the rear I/O shield. You will need to supply a LGA 1150 processor, DDR3 memory modules, storage drives, a power supply and a case.

Which memory capacity and speed should I pick for this H81 board?

The board supports dual-channel DDR3 up to 16 GB total. Standard speeds are 1600, 1333 and 1066 MHz; higher speeds such as 2400, 2200, 2000 or 1800 MHz are listed as overclocking options.

What does the single PCIe 3.0 x16 slot mean for a graphics card in a real build?

The primary slot runs at PCIe 3.0 x16, giving a modern graphics card full bandwidth. A second x16-size slot is wired for PCIe 2.0 x4 speeds, and two legacy PCI slots are also provided.
