ASUS showed off its PRIME X299-A socket LGA2066 motherboard. The PRIME series consists of ASUS' mainline motherboards, and a consistent product design theme follows through the entire lineup. We reckon that the PRIME X299-A will be the "entry-level" socket LGA2066 offering by ASUS, topped by the PRIME X299-PRO and PRIME X299-Deluxe. Built in the ATX form-factor, the board draws power from 24-pin ATX, 8-pin EPS, and a 4-pin ATX power connector. It uses a simple 8-phase VRM to condition power for the CPU. The LGA2066 socket is wired to eight DDR4 DIMM slots, in addition to three PCI-Express 3.0 x16 slots (x16/x16/NC or x16/x8/x8). Two close-ended PCI-Express 3.0 x4 and an x1 slot make for the rest of the expansion.

Storage connectivity includes two 32 Gb/s M.2 slots (one 80 mm and the other 110 mm), and eight SATA 6 Gb/s. There's just the one gigabit Ethernet interface driven by an Intel I219-V controller, and an onboard audio solution featuring Realtek ALC1220 (120 dBA SNR) CODEC, audio-grade capacitors, and ground-layer isolation. This board could be priced around the $200 mark.
