ASUS B85M-E LGA 1150 motherboard

The ASUS B85M-E is a Micro ATX motherboard built on the Intel B85 chipset for LGA 1150 processors. It supports DDR3 memory up to 32 GB total capacity. The board ships with a chassis I/O back panel and one SATA cable, supplied without original packaging.

Builders upgrading or repairing LGA 1150 systems

This board suits anyone replacing a failed B85 motherboard or assembling a cost‑effective DDR3 system using existing LGA 1150 CPUs and memory. Buyers who need newer socket compatibility, higher memory limits or modern storage interfaces should consider a different platform.

DDR3 32 GB maximum memory support

The 32 GB DDR3 ceiling is the key figure that determines whether this board fits the planned build. If the intended workload requires more memory or a different memory type, this motherboard will not meet the requirement.

Questions about this item

Does the metal battery supplied with the board need periodic replacement?

The included metal battery is a standard coin cell that maintains BIOS settings when the system is off; it typically lasts several years before a swap is needed.

What component limits sustained loads on the Intel B85 chipset first?

The B85 chipset itself is the primary thermal limit during prolonged heavy I/O, as it handles all PCIe and SATA traffic without active cooling.

How much power does the board draw and how hot or loud does it get when running all day?

With no VRM heatsinks and a passive chipset, the board runs warm under continuous load but stays silent because it relies entirely on case airflow for cooling.
