Socket LGA 1150 Micro ATX board
The MSI H81M-E33 is a Micro ATX motherboard built around the Intel H81 chipset for fourth-generation Intel Core i7, i5, i3, Pentium and Celeron processors using the LGA 1150 socket. It provides a compact foundation for office workstations or basic home PCs where a full-size ATX board is unnecessary.
Dual-channel DDR3 and essential I/O
The board supports dual-channel DDR3 memory at 1600, 1333 and 1066 MHz up to a total of 16 GB. A single PCIe 2.0 x16 slot and one PCIe x1 slot handle graphics or add-in cards, while two SATA III and two SATA II ports connect storage drives. Rear I/O includes two USB 3.0 ports, a Realtek 8111G Gigabit LAN jack and 8.1-channel audio from the Realtek ALC887 codec.
16 GB ceiling and limited expansion
The 16 GB memory ceiling suits everyday multitasking and light content creation but leaves no headroom for heavier workloads. Only one x16 slot and one x1 slot restrict multi-GPU setups or multiple high-bandwidth add-in cards, and the four SATA ports limit the number of internal drives without extra controllers.

Questions about this item
Does the included CMOS battery need replacing and how often?
A CMOS battery is supplied with the board; replace it when the system clock drifts or BIOS settings clear.
Which part limits expansion first when adding more drives?
Four SATA ports are provided — two SATA III and two SATA II — so the port count is the first constraint.
How loud or hot does the board run during all-day operation?
Passive chipset cooling and no onboard fan keep noise minimal; heat output stays low under typical loads.
