One of the highlights of this motherboard is the presence of two ports of the new USB 3.1 standard, implemented through a PCI Express x4 card, shown in Figure 7. This card uses an ASMedia ASM1142 chip and uses two PCI Express lanes.
USB 3.1 ports have a maximum theoretical bandwidth of 10 Gbps (1 GB/s), which is twice the bandwidth offered by USB 3.0 ports.
As you can see in Figure 8, this card has one USB 3.1 type C (at the left) and one type A (at the right) ports. The new type C connector is amazing because, besides being reversible (you can plug it in any position), it is compatible with video connections and charge plugs (it supports up to 100 W of power). Thus, it should become a universal connector standard in the near future.
This motherboard comes with two BIOS chips, selectable on a jumper, as shown in Figure 9. It also supports TPM (Trusted Platform Module), which stores criptographic keys and improves the system security (connector also shown in Figure 9).
In Figure 8, you can see the accessories that come with the ASRock Fatal1ty Z97X Killer/3.1.
