MSI's Micro-ATX LGA 1155 Motherboard Lineup Revealed

Recently, picture previews of LGA 1155 motherboards have been popping around everywhere on the Web, but most of these centered on more expensive, full-ATX models, so today we are focusing on MSI's micro-ATX lineup which consists of at least four products.

Starting things off is the most basic model, the H67MS-E33, that comes with a pretty simple power delivery circuit as well as with just one x16 PCI Express slot.

However, users get three x1 slots, four SATA 3Gbps and two SATA 6Gbps ports, six USB 2.0 ports, a D-sub, DVI and HDMI port being placed on the board's backpanel.

As you can see, there are no PCI slots available so users with older add-in cards will have to buy new ones that use the PCIe standard slot in order to retain the functionality of their old computer.

Moving up in MSI's lineup, we find the H67MS-E43 which adds a pair of memory slots, although it features the same layout as that of the E33, its power delivery circuit also being improved as this motherboard receives an extra phase and better chokes.

Next in line is the H67MA-E45 that brings just some minor improvements compared to the E43, as two of the USB 2.0 ports have been replaced with a pair of SuperSpeed USB 3.0 ports, Firewire support being also added to the mix.

And finally, we arrive to the forth and last member of MSI's mATX lineup, the H67MA-ED55 coming as a huge improvement over the E45 as the Taiwanese company has now opted for a 10-phase power regulation circuit, covered by two heatsinks connected via a small heatpipe.



Furthermore, the ED55 also features a pair of PCIe x16 slots as well as on-board power and reset buttons, a voltage readout point being included right below the memory slots.

As far as we can tell, MSI will most surely release a few other mATX Sandy Bridge boards in the future as no Intel H61-based model has been announced until now. (via SemiAccurate)
