Lab501 snapped a picture of Gigabyte's Z87X-OC, the company's upcoming flagship motherboard for Intel's Haswell processor. The LGA1150 based motherboard is still a prototype, the layout if subject to change and the final color scheme and heatsink design has yet to be determined.
The motherboard features 8-phase VRM that draws power from 4-pin ATX and 8-pin EPS connectors, in addition to the 24-pin ATX connector. In order to further stabilize the board's various power domains, you can plug in a 6-pin PCIe power connector, but this is optional. The Z87X-OC gives overclockers a high degree of on-the-fly voltage control and includes measurement points.
The LGA1150 socket on the GIGABYTE Z87X-OC is wired to four DDR3 DIMM slots supporting up to 64 GB of dual-channel DDR3 memory, and three PCI-Express 3.0 x16 slots (x16/NC/NC ; x8/NC/x8 ; x8/x4/x4). The bottommost long PCIe slot appears to be electrical Gen 2.0 x4, wired to the PCH. A PCI-Express 2.0 x1, and two legacy PCI slots find room in the middle.
Connectivity includes six SATA 6 Gb/s internal ports, a total of nine USB 3.0 ports (six of which are driven by third-party controllers), HDMI and DisplayPort display outputs, 8-channel HD audio, PS/2 mouse/keyboard combo, and gigabit Ethernet.
Additionally, Lab501 also published pictures and details of the GIGABYTE GA-Z87X-UD5H, GA-Z87X-UD3H and GA-Z87X-D3H motherboards over here.
