Socket LGA 1151 MicroATX Motherboard

The ASUS PRIME B250M-A is a new Intel motherboard built on the B250 chipset with a MicroATX form factor. It supports LGA 1151 processors including Core i7, i5, i3, Pentium and Celeron models. The board includes one M.2 slot and a single PCI Express x16 slot for graphics or expansion cards.

Builders needing a compact B250 board

This board suits system builders assembling a compact desktop on the LGA 1151 platform who require a single M.2 drive and one full-size PCIe slot. It is not suited for buyers who need multiple M.2 drives, additional PCIe expansion slots, or a larger ATX form factor with more rear I/O connectivity.

B250 chipset with one M.2 slot

The defining specification is the B250 chipset paired with a single M.2 slot, which determines both the CPU generation compatibility and the maximum number of M.2 devices supported. Verify that your chosen processor and storage plan match this configuration before purchase.

Questions about this item

Does the motherboard come with SATA cables or a driver disc, or must they be purchased separately?

Only the motherboard and I/O shield are included; SATA cables, driver disc, Wi-Fi antenna and all other accessories are not supplied and must be bought separately.

Which capacity of the single M.2 slot should I choose for a boot drive versus bulk storage?

The board provides one M.2 slot; select a 250 GB or larger drive for the operating system and add a separate SATA drive if you need more space.

What does the LGA 1151 socket mean for processor choice when the board is installed in a case?

The LGA 1151 socket accepts Intel Core i7, i5, i3, Pentium or Celeron CPUs that use that socket, so the processor must match the 1151 pin layout.
