The Z77A-G45 is going to be one of the more affordable socket LGA1155 motherboards based on the Intel Z77 chipset, by MSI. The Z77A series from MSI starts with high end Z77A-GD80, Z77A-GD65, and Z77A-GD55. eTeknix scored pictures of the Z77A-G45. The G45 uses a simple 6-phase VRM to power the LGA1155 CPU. It doesn't cheap out on cooling for the MOSFETs. The socket is wired to four DDR3 DIMM slots, supporting dual-channel DDR3 memory.

The expansion slot area is identical to that of all the other Z77A series motherboards, consisting of two PCI-Express 3.0 x16 (x8/x8 when both are populated), one PCI-Express 2.0 x16 (electrical x4), and four PCI-Express 2.0 x1. MSI gave legacy PCI the boot. Strangely enough, this board features NVIDIA SLI support (something unusual for a "G45" model, as "D" in the model name signifies SLI support. The motherboard doesn't appear to use third-party storage or USB 3.0 controllers. All six SATA ports are internal, wired to the Z77 PCH, and consist of two SATA 6 Gb/s, and four SATA 3 Gb/s. All four USB 3.0 ports (two on the rear-panel, two via front-panel header) are wired to the PCH.Display connectivity on this board includes one each of DVI, HDMI, and D-Sub. Other connectivity includes 8-channel HD audio with optical and coaxial SPDIF outptus, featuring THX TruStudio Pro, a number of USB 2.0 ports, and gigabit Ethernet. There are some features overclockers will handy, these include MSI's ClickBIOS graphical UEFI setup program, consolidated voltage measurement solder points, MSI InstantOC, and support for DDR3-2667 MHz via overclocking.
