Mini-ITX board for fourth-generation Intel CPUs

This motherboard uses the Intel B85 chipset and an LGA 1150 socket to support fourth-generation Intel Core i7, i5, i3, Pentium and Celeron processors. It provides a compact foundation for a small-form-factor desktop build.

Suits builders reusing DDR3 memory and SATA storage

The board accepts up to 16 GB of dual-channel DDR3 at 1600, 1333 or 1066 MHz and offers four SATA III ports for drives. It is not suitable for newer CPU generations or memory types that require a different socket or chipset.

Single PCIe 3.0 x16 slot defines expansion

Only one full-size PCI Express 3.0 x16 slot is available alongside a half-size mini-PCIe slot, so the system can host just one full-length add-in card such as a graphics adapter.

Questions about this item

How loud or hot does the MSI B85I get when running a 4th generation Intel Core processor all day?

The board uses the Intel B85 chipset and a single PCIe 3.0 x16 slot, so heat output depends on the CPU cooler and case airflow you provide.

What memory and storage must I already own to use this motherboard?

You need DDR3 modules running at 1600, 1333 or 1066 MHz up to 16 GB total, plus SATA drives for the four SATA III ports.

Will my older PCI Express 2.0 graphics card work in the PCIe 3.0 x16 slot?

Yes, the slot is backward compatible, so a PCIe 2.0 card will run at its native speed in the x16 slot.
