Intel B250 micro-ATX motherboard for 6th/7th gen

This micro-ATX board uses the Intel B250 chipset and an LGA 1151 socket for 6th and 7th generation Intel Core i3, i5 and i7 processors, plus Pentium and Celeron models. It supports dual-channel DDR4 memory at 2400 or 2133 MHz up to 64 GB. The layout fits smaller cases while keeping two full-length PCIe 3.0 x16 slots and two PCIe 3.0 x1 slots.

Refurbished unit with minimal accessories

The product is sold as refurbished stock graded 90% to 80% new and will show signs of use. The package contains only the motherboard, one SATA cable, a metal battery and a chassis I/O back panel. No original box, driver media or extra cables are included, so builders must source any additional SATA cables, M.2 screws or front-panel USB headers themselves.

Straightforward drop-in for LGA 1151 builds

Installation follows the standard micro-ATX pattern: align the standoffs, secure the board, connect the 24-pin and CPU power headers, then fit memory and expansion cards. The limited accessory kit means missing M.2 standoffs or front-panel USB cables are the most common omissions. Buyers needing Wi-Fi, Bluetooth, additional M.2 slots or newer CPU generations should choose a different platform.

Questions about this item

Will the LGA 1151 socket need servicing or replacement later?

The socket is fixed to the board; if pins bend or the CPU fails you replace the processor, not the socket itself.

What limits the Micro ATX board first under sustained load?

The 23.6 x 20.0 cm layout has only two DDR4 slots and two PCIe 3.0 x16 slots, so memory capacity tops out at 64 GB and expansion cards compete for the x16/x4 lanes.

How much heat and noise does the Intel I219-V LAN and Realtek ALC892 audio generate all day?

Both controllers are low-power integrated chips; they add negligible heat and no audible noise during continuous operation.
