ASUS B85-PRO GAMER LGA 1150 motherboard

This ATX motherboard uses the Intel B85 chipset and the LGA 1150 socket for fourth-generation Intel Core processors. It supports DDR3 memory up to 32 GB total capacity. The board targets builders assembling or repairing systems on this legacy platform.

Suitable for LGA 1150 DDR3 builds

This board fits users replacing a failed B85 motherboard or building a cost-focused LGA 1150 system with DDR3 memory. It is not suited for builders who require a newer CPU socket, different memory type, or storage interfaces not present on the Intel B85 chipset.

Maximum DDR3 memory of 32 GB

The chipset and board design limit total system memory to 32 GB across the available DDR3 slots. Verify that your planned memory kit stays within this ceiling before purchasing.

Questions about this item

How do I install this ASUS B85-PRO GAMER motherboard into an ATX case and which step is often missed?

Mount the board using ATX standoffs, connect the 24-pin and CPU power cables, then fit the supplied I/O back panel before securing the motherboard — many builders forget the back panel until the board is already screwed down.

What maintenance or replacement will this motherboard need over time?

The included CMOS battery will eventually lose charge and should be swapped when the system clock drifts or BIOS settings reset; the supplied battery lets you do this immediately.

What memory limit appears first when pushing this board with DDR3 modules?

The chipset caps total memory at 32 GB across the DDR3 slots, so you cannot exceed that capacity regardless of module density.
