LGA 1155 Micro ATX Motherboard

The MSI B75MA-E33 is an Intel B75 micro ATX motherboard built for the LGA 1155 socket. It accepts Core i7, i5, i3, Pentium and Celeron processors and fits compact chassis designs. The board provides a foundation for general desktop builds and office upgrades.

Dual Channel DDR3 Support

Two 240-pin slots run dual-channel DDR3 at 1066, 1333 and 1600 MHz natively. With a 22 nm CPU the memory controller can reach 1800, 2000, 2200 and 2400 MHz through overclocking. This headroom lets faster modules operate at rated speeds without changing other components.

Core Connectivity and Expansion

One PCI Express 3.0 x16 slot handles a discrete graphics card while a single PCI Express x1 and one legacy PCI slot cover add-in cards. Storage connects through one SATA 6Gb/s port. Rear I/O supplies HDMI video, two USB 3.0 ports, four USB 2.0/1.1 ports and dual PS/2 connectors. Realtek ALC887 8-channel audio and 8111E Gigabit LAN complete the essential feature set.
