The Realtek ALC1220 is the new audio codec we see on Z270 motherboards; it offers 120dB SNR with an integrated headphone amplifier. ASRock uses the integrate amplifier for the rear IO headphone jack and has added a Texas Instruments NE5532 for the front panel headphone output. Nichicon Gold series audio capacitors are used to improve audio quality as is a very intricate PCB division scheme to isolate the audio PCB from the rest of the motherboard.

The AQUANTIA AQtion AQC108 is the 5Gbit NIC with integrated PHY. It is backward compatible with 2.5G, 1G, and 100M Ethernet, and has a 3W TDP, so ASRock has a heat sink on it. Wireless AC is provided by a 2x2 unit, the Intel Wireless-AC 3160NGW.

ASRock also is providing two Intel NICs. An i219v is the PHY for the integrated MAC in the PCH, and an i211AT standalone NIC is used for the second.

ASMedia's ASM2142 USB 3.1 controller is found on the rear of the PCB and provide the USB 3.1 type-A and type-C ports. The type-C port requires a type-C switch and CC logic controller. The ASMedia ASM1543 is used for this purpose.

An ASMedia ASM1184e PCI-E hub is used to expand PCI-E lanes for different devices like the SATA controllers. An ASMedia ASM1074 USB 3.0 hub is used to expand one USB 3.0 port into four for the two USB 3.0 headers.

The main SuperIO is the NCT6791D, and it provides monitoring and control over voltage, temperature, and fans. To provide extra features such as RGB LEDs, a nuvoTon N76E885 is used.

To improve BCLK overclocking, an IDT6V41642B clock buffer is present. Multiple ASMedia ASM1480s are used to switch PCI-E bandwidth across the motherboard.
