Computex 2017 - We have seen some impressive X299 motherboards, but none are as big as one we spotted at Biostar's booth at Computex 2017. The X299GT9 is a monster motherboard that comes in the E-ATX form factor, which allows for a significantly wider PCB. The motherboard features multiple PCI-E x16 slots, two U.2 ports, an M.2 slot, many USB 3.0 internal headers, and a hefty VRM.
Hidden under a metal veil is an Intel 1Gbit NIC as well as an Intel 10Gbit NIC. Intel's X550AT is employed to drive the higher networking speeds. The PCI-E layout is x16/x16/x8/x4/x4/x4/x4 and there are four SATA6Gb/s ports on the right of the motherboard. The motherboard does support USB 3.1 and carries a 14-phase VRM. We don't know much more about the motherboard, but its size is impressive, and hopefully we will get one in for review.
