B85 micro-ATX board for LGA 1150 CPUs

This micro-ATX motherboard uses the Intel B85 chipset and fits LGA 1150 processors including Core i7, i5, i3, Pentium and Celeron. It targets office builds and basic home systems that need legacy expansion slots. The board delivers essential modern connectivity without enthusiast features.

Four DDR3 slots and mixed PCIe plus PCI

Four 240-pin slots support DDR3 1600 and 1333 in dual-channel mode up to 32 GB total. One PCI Express 3.0 x16 slot and one PCI Express x16 slot sit alongside two classic PCI slots for older add-in cards. SATA 6 Gb/s and 3 Gb/s ports provide six drive connections.

PCIe 3.0 x16 and SATA 6 Gb/s limits

The single PCI Express 3.0 x16 slot caps graphics bandwidth at the 3.0 specification. Integrated graphics output via HDMI works only when the installed CPU includes an onboard GPU. Gigabit LAN tops out at 1000 Mbps and audio reaches 7.1 channels.
