Connectique et I/O
Gigabyte equipped the X99 Ultra Gaming with ten angled SATA ports. All ports offer
6Gbps bandwidth and they've been wired directly to the X99 PCH. Two SATA ports can also be combined to form one SATA Express port. There is also an U.2 connector as well as two M.2 slots and all of them feature x4 PCI Express 3.0 lanes allowing for up to 32 Gbps of bandwidth. Overall storage flexibility is great and with this motherboard it's piece of cake to assemble gaming systems, workstations as well as enthusiasts rigs with plenty of fast drives. Unfortunately there is no debug LED and there is also no power/reset button.
In total there are five fan headers on the Gigabyte X99 Ultra Gaming. This basically enough for to provide a high-end system with fresh air, although it would have been nice to find a few more for additional flexibility when building rigs. All headers offer 4 Pins, which means fan speeds can be regulated from within Windows, via Gigabytes Software.
Looking at the external connectors directly at the I/O panel Gigabyte equipped the X99 Ultra Gaming with one PS/2 connector, six USB 3.0 ports,
two USB 3.1 ports (1 x Type-A, 1 x Type-C), two Gigabit ethernet ports as well as an optical out and an analogue audio panel.
