MSI released details about its upcoming value socket LGA1155 motherboard, the B75MA-P45. MSI finds the B75 PCH a worthy option over the current-generation H61 PCH, and could hence price its B75-based motherboards competitively, to capture the entry-level LGA1155 market. The B75MA-P45 comes with out of the box support for 22 nm "Ivy Bridge" Core processors, apart from current-generation "Sandy Bridge" ones. The B75MA-P45 packs a simple 5-phase VRM to power the LGA1155 CPU. The CPU is wired to four DDR3 DIMM slots, supporting dual-channel DDR3-1600 MHz memory.

Expansion slots include one PCI-Express 3.0 x16, one PCI-Express 2.0 x1, and a legacy PCI. The legacy PCI logic is reintegrated with the PCH, and so the board doesn't use any bridge chips, further, since USB 3.0 and SATA 6 Gb/s are integrated with the PCH, MSI didn't add third-party controllers handling the two. SATA connectivity includes one SATA 6 Gb/s, and five SATA 3 Gb/s. The PCH gives out four USB 3.0 ports, two of which are found on the rear panel, two via internal header. Display connectivity includes DVI and D-Sub. 6-channel HD audio, gigabit Ethernet, and legacy PS/2 connectors complete the package. The board is driven by UEFI firmware (5 MB ME 8.0), with a graphical setup program. The B75MA-P45 is said to capture a price-point under US $100.
