Socket LGA 1150 micro-ATX motherboard

The ASUS B85M-D fits Intel fourth-generation Core i7, i5, i3, Pentium and Celeron processors in a 22.6 by 18.0 cm micro-ATX layout. It provides dual-channel DDR3 memory support up to 16 GB at 1600, 1333 or 1066 MHz. The board targets budget builds that need legacy CPU compatibility.

Thermals noise and power draw

The Intel B85 chipset and simple voltage-regulation design keep idle power low and produce minimal heat under typical desktop loads. Passive chipset cooling and standard fan headers run quietly in ordinary chassis airflow. No extra power connectors beyond the main ATX and CPU plugs are required.

Build integration

One PCI Express 3.0 x16 slot and two PCI Express 2.0 x1 slots handle a graphics card and add-in boards. Six SATA ports — four SATA III and two SATA II — connect drives without an extra controller. Rear I/O supplies two USB 3.0 and two USB 2.0 ports; internal headers add two more USB 3.0 and four USB 2.0 connections. Gigabit LAN and 7.1-channel Realtek ALC887 audio are onboard. The box includes the motherboard, one SATA cable and the I/O shield.

Questions about this item

How do I install this Micro ATX board into a chassis and which step is often missed?

Mount the 22.6 x 18.0 cm board using the standard Micro ATX standoff pattern, fit the supplied I/O shield first, then connect the 24-pin and 4-pin power cables before adding any expansion cards.

What component will need replacement during the life of this motherboard?

The onboard metal battery maintains BIOS settings and will eventually run down, requiring a simple swap to keep the clock and CMOS data intact.

Which memory limit is reached first when populating the DIMM slots?

Two DDR3 slots support up to 16 GB total at 1600/1333/1066 MHz, so the 16 GB ceiling is hit before any speed limit.
