Socket LGA 1151 B365 Platform

This Micro ATX board accepts 9th and 8th Generation Intel Core i9, i7, i5, i3, Pentium and Celeron processors in the LGA 1151 package. It is not compatible with older LGA 1151 CPUs. The Intel B365 chipset provides a stable foundation for office workstations and entry-level gaming builds.

Dual-Channel DDR4 and Expansion Slots

Four 288-pin slots support up to 64 GB of DDR4 2666, 2400 or 2133 memory in dual-channel mode. A PCI Express 3.0 x16 slot, one x4 slot and one x1 slot handle graphics and add-in cards. Six SATA 6Gb/s ports and an M.2 Socket 3 M-key connector for 2242, 2260 or 2280 SATA and PCIe SSDs cover storage needs.

Realtek Audio, LAN and RGB Fusion

The Realtek ALC887 codec delivers 2, 4, 5.1 or 7.1-channel output with S/PDIF support. A Realtek GbE LAN chip includes 15 KV surge protection and bandwidth management. RGB Fusion drives 7-colour LED strips. Smart Fan 5 adds multiple temperature sensors, hybrid headers and fan-stop control, while anti-sulfur resistors and DualBIOS improve longevity.
