Along with the H55MA-E43, MSI Computer Japan announced the H55M-P33, a LGA1156 mainboard with Intel’s H55 Express chipset onboard, last week. Along with DVI-I, D-Sub15, 7.1ch analog audio, and Ethernet ports, this board comes with Active Phase Switching, a power-saving (and money-saving, and circuit-saving) feature that controls power flow to components that actually require it. Comes with four RAM slots for a maximum of 16GB dual-channel memory access.

The H55M-P33 will be available at the end of this month.
