Lab501 also got to see a prototype of MSI's Z87A Gaming Series motherboard. This motherboard comes with 16-phase VRM that draws power from two 8-pin EPS connectors. There are four DDR3 memory slots for up to 64GB of dual-channel memory, three PCIe 3.0 x16 slots in x16/NC/NC or x8/x8/NC or x8/x4/x4 configurations, depending on how they're populated, and four PCIe x1 slots.
Storage connectivity on the Z87A Gaming Series includes eight SATA 6 Gb/s slots, two of which are driven by a third-party controller. 8-channel HD audio, gigabit Ethernet, eight USB 3.0 ports (six on the rear panel, two by header), dual-HDMI and DisplayPort display outputs; effectively make for the rest of the board. The same exact PCB could be used to create two SKUs, the Z87A Gaming Series, and the Z87A-GD65.
While the basics of the motherboard are more or less finalized, the PCB color, component color scheme and heatsinks are yet to be decided.
