Socket LGA 1151 Micro ATX Board

This motherboard uses the Intel B250 chipset and fits Micro ATX cases. It accepts Core i7, i5, i3, Pentium and Celeron processors built for the LGA 1151 socket. Four DDR4 slots support up to 64 GB of memory running at 2400 or 2133 MT/s in dual-channel mode.

Check CPU Generation Before Buying

The board does not work with 8th Generation Intel CPUs despite sharing the same physical socket. Verify that your processor is a 6th or 7th Generation part before ordering. Ensure your chassis has a Micro ATX mounting pattern and that your power supply provides the standard 24-pin and 4-pin CPU connectors required by this form factor.

Integrated Video Outputs And M.2 Flexibility

Onboard graphics from a compatible CPU can drive displays through HDMI, DVI-D and DisplayPort 1.2 connections. The single M.2 Socket 3 with M Key accepts 2242, 2260 or 2280 drives operating in either SATA or PCIe x2 mode, while a second M.2 slot supports PCIe x4 devices. Six SATA 6Gb/s ports and one PCIe x1 slot complete the expansion options.

Questions about this item

Does the board come with an I/O shield and cables, or must I buy them separately?

The motherboard ships with an I/O shield, two SATA 6Gb/s cables, a driver disc and a quick-start guide. No CPU, DDR4 memory, M.2 SSD or case standoffs are included.

Should I choose DDR4 2400 or DDR4 2133 modules for the four 288-pin slots?

Both standards work in the four slots up to 64 GB total. DDR4 2400 runs at its rated speed; DDR4 2133 runs at 2133 MHz. Pick 2400 for the highest supported frequency.

What does the HDMI 4096 x 2160 @ 24 Hz figure mean when I plug in a monitor?

The integrated Intel HD Graphics can drive one HDMI display at up to 4096 x 2160 resolution at 24 Hz. Higher refresh rates at that resolution are not supported over HDMI on this board.
