Verdict

The ASUS B85M-E is a Micro-ATX motherboard built on the Intel B85 Express chipset, featuring an LGA 1150 socket that supports 4th generation Intel Core i7, i5, i3, Pentium, and Celeron processors. Key specifications include four DDR3 DIMM slots supporting up to 32GB of 1600MHz memory, a PCIe 3.0/2.0 x16 slot, and a comprehensive rear I/O offering DisplayPort, HDMI, DVI, and VGA outputs for flexible display configurations. Its primary advantages are its robust durability as a 'Corporate Stable Model' (CSM), high-quality solid capacitors, and user-friendly features like UEFI BIOS and Fan Xpert 2 for balanced cooling. However, main drawbacks include the lack of CPU overclocking support due to the B85 chipset limitations and a restricted 24Hz refresh rate when outputting 4K resolution via HDMI.
