LGA 1150 Micro ATX board

The MSI H81M-P33 PLUS is a Micro ATX motherboard built around the Intel H81 chipset for LGA 1150 processors. It accepts 4th generation Core i7, i5, i3, Pentium and Celeron CPUs. Dual-channel DDR3 memory runs at 1600, 1333 or 1066 MHz up to 16 GB total. A single PCIe 2.0 x16 slot handles a graphics card.

Best for basic builds, not for newer CPUs

This board suits budget office PCs, home servers or legacy upgrades that need LGA 1150 and DDR3. It provides two SATA III and two SATA II ports, Realtek ALC887 audio and a Realtek RTL8111G LAN controller. Builders targeting 6th generation or later Intel processors, or any AMD platform, must choose a different socket and chipset.

One PCIe 2.0 x16 slot decides GPU choice

The only full-length expansion slot is a PCIe 2.0 x16 connector, so graphics cards are limited to that interface speed. A single PCIe 2.0 x1 slot is available for add-in cards such as Wi-Fi or extra USB controllers. Rear I/O includes two USB 3.1 Gen1 ports and four USB 2.0 ports, with four more USB 2.0 headers onboard.

Questions about this item

What size case and screw pattern does this Micro ATX board need?

It fits any Micro ATX or larger chassis using the standard mounting holes for this form factor.

Which memory slots must be filled first for dual-channel DDR3 1600/1333/1066 operation?

Populate the two slots of the same colour — usually DIMM1 and DIMM2 — so the memory controller enables dual-channel mode.

What component should be replaced when the system loses date, time or BIOS settings after power-off?

The included CMOS battery on the board; swap it with an identical coin cell when settings no longer persist.
