Compact B250 platform for 6th

The Micro ATX board uses the Intel B250 chipset and an LGA 1151 socket to support Core i3, i5, i7, Pentium and Celeron processors from those two generations. It targets builders who need a small-form-factor foundation for office work, home servers or budget gaming rigs.

Dual-channel DDR4 up to 32 GB

Two memory slots accept DDR4 2400 or 2133 modules for a 32 GB ceiling, enough for multitasking and light content creation but tight for heavy virtualization. A single PCIe 3.0 x16 slot handles a graphics card while two x1 slots add capture cards or extra I/O.

Realtek audio, Gigabit LAN and generous USB count

The ALC887 codec delivers 7.1-channel output and the RTL8111H controller provides wired 1 GbE networking. Six USB 3.1 Gen1 ports and six USB 2.0 ports are split between rear panel and internal headers, reducing the need for extra hubs. A single SATA cable, CMOS battery and I/O shield ship in the box.

Questions about this item

Will the LGA 1151 socket accept the 6th generation Intel Core i5 I already own?

Yes, the LGA 1151 socket supports 6th and 7th generation Intel Core i3, i5 and i7 processors as well as Pentium and Celeron models with the same pin layout.

How can I confirm the Realtek ALC887 audio is delivering 7.1 channel output?

Open the Realtek Audio Console in Windows, select 7.1 speaker configuration and run the speaker test; each of the eight channels should play a distinct tone.

Which cables and brackets come in the box so I know what to buy separately?

The package includes the motherboard, a CMOS battery, one SATA cable and the chassis I/O back panel; CPU cooler, additional SATA cables, M.2 screw and memory modules are not included.
