The Realtek ALC1220 is rated for 120dB SNR for the main headphone output. The codec also has an integrated amplifier for the headphone/speaker jack, and ASRock added a Texas Instruments NE5532 to amplify the front panel header output. Gold electrolytic audio capacitors are used to improve audio quality, as is a physical PCB divide.

We find the Aquantia AQC107 NBase-T controller which supports 10Gbit, 5, 2.5, 1, and 100Mbit Ethernet. It is part of a new class of NICs and performs quite well. We find two Intel i211AT 1Gbit NICs on the motherboard as well.

Two Pericom PI3EQX USB 3.1 re-drivers improve USB 3.1 signals from the X399 chipset. An ASMedia ASM1543 type-C switch and CC logic chip are used for the rear IO panel's type-C port. A FlashBack IC provides the USB BIOS recovery feature.

The main SuperIO is a NuvoTon NCT6779D and provides system monitoring and PS/2 on the rear IO. A nuvoton N76E885AT20 provides RGB LED control, and a drivers and receivers chip (labeled 232GG) provides the COM port header.
