ASUS B85-PRO LGA 1150 motherboard

This ATX Intel board fits LGA 1150 processors from the 4th generation Core i7, i5, i3, Pentium and Celeron families. It is built around the Intel B85 chipset for standard desktop workloads. The board targets system builders who need a reliable platform for office or home PCs.

Dual-channel DDR3 up to 32 GB

Memory runs at 1600, 1333 or 1066 MHz across four DIMM slots with a 32 GB ceiling. This capacity limit is the key figure when planning a multitasking or virtualisation build. Populate all slots to reach the maximum supported amount.

Passive chipset cooling and standard ATX power

The B85 chipset uses a heatsink without a fan, so chipset noise is absent in normal use. CPU thermals depend entirely on the cooler you install. The board draws power through regular ATX and 4-pin CPU connectors with no extra power phases.
