ASRock showed off its premium gaming-grade X299 Fatal1ty Professional Gaming i9 and X299 Killer SLI/ac motherboards. The two boards are based on a common PCB, but differ with the former featuring 10 GbE network connectivity and Creative Sound Blaster Cinema audio DSP, while the latter lacks them. If you want the feature-set of the X299 Killer SLI/ac but the white+black color scheme isn't rubbing of on you, ASRock has you covered with the X299 Fatal1ty Gaming K6. Drawing power from a combination of 24-pin ATX and 8-pin EPS connectors, the boards employ a 14-phase VRM to condition power to the CPU, which is wired to eight DDR4 DIMM slots, and four PCI-Express 3.0 x16.

Storage connectivity on the boards includes three 32 Gb/s M.2 slots, and six SATA 6 Gb/s ports. Both boards further feature two USB 3.1 ports (of which one is type-C), about 8 USB 3.0 ports, and network connectivity that includes 802.11ac WLAN, Bluetooth 4.1, and at least one gigabit Ethernet connection driven by an Intel i219-V controller. The Fatal1ty Gaming i9 tops this with Aquantia AQC107 controller-driven 10 GbE. The two feature Aura Sync RGB headers.
