ASUS uses the Realtek ALC1220, and also integrated Nichicon Gold series capacitors and physical PCB division to improve audio quality.

Aquantia's 5Gbit NBase-T NIC, the AQC108 is used to provide 5Gbit/2.5Gbit/1Gbit/100Mbit LAN. There is also an Intel i219v PHYS used to complement the PCH's integrated MAC for a 1Gbit Intel LAN port.

An ASMedia ASM3142 is used to provide USB 3.1 capabilities, and an ASM1543 is used as the type-C switch and CC logic chip. An IDT 6V41638B is used as a clock generator for better BCLK overclocking margins.

The motherboard features only six ASMedia quick switches, and they are used for the PCI-E lanes from the CPU. There are no other PCI-E quick switches, which is kind of impressive. The nuvoTon NCT6793D is used as the SuperIO and provides the PS/2 on the rear IO, fan control, and system monitoring.

The motherboard has two 128Mbit/16MB BIOS ROMs, but it also has an EEPROM right next to the BIOS ROMs, presumably to store profiles. The motherboard also has the BIOS chip that supports BIOS flashback. We find a few custom chips, such as the ROG chip which is an embedded controller used to provide extra overclocking/ROG features.

A custom chip labeled TPU is also used to provide extra functionality on the motherboard. An AURA chip provides RGB LED support.

An ASMedia ASM1442K is used as a level shifter and provides the HDMI port on the rear IO. A chip labeled RC02881PY is found on the motherboard (same chip was found on the Maximus IX Apex) and I think it's either a digital RGB controller, an extra clock generator (I mean it does have a crystal), or an extra OC feature controller (like for the condensation detection).
