Prepare for the Ivy Bridge.
The MSI Z77A-GD55 is a standard ATX sized motherboard. The color scheme on the entire board is black and blue, with the heatsinks standing out as a subtle design which blends style with effective usage.
On the rear I/O panel we see the PS/2 port, 4x USB 2.0 ports and 2x USB 3.0 ports, a VGA, DVI and HDMI port. Finishing up we have the LAN port and the 6 audio jacks, plus SPDIF.
Moving down we see the two PCIe Gen 3.0 x16 slots as well as a PCIe Gen 2.0 x16 slot. There and additional 4x PCIe Gen 2.0 x1 slots for expansion cards.
Moving on we have the USB 2.0 jumpers on the bottom right, close to the SATA ports a little further up. There are 2x SATA 3 (6Gbps) and 4x SATA 2 (3Gbps) ports, colored in white and black respectively. Just a bit on the top is also the USB 3.0 jumper.
All the way to the top, next to the 4x DIMM slots, we have the Power, Reset and OC Genie II button. When using OC Genie II, the standard overclock applied by the Z77A-GD55 is 4.2GHz.
