GIGABYTE uses the Realtek ALC1220, which offers up to 120dB SNR for the headphone output and has an integrated headphone amplifier. A LME49720 chip is used to provide the audio circuit with its own dedicated analog power source. The ESS Sabre DAC, the SABRE ES9018 with 121dB DNR, is used to compliment the ALC1220. WIMA film capacitors and Nichicon Fine Gold capacitors are used to improve audio quality.

The Killer e2500 NIC is used as one of the Gbit NICs, while an Intel i219v is used to provide the second Gbit NIC. The rear IO's USB 3.1 comes from an ASMedia ASM3142 USB 3.1 controller, and a Texas Instruments type-C switch, the HD3220 is used to switch the type-C port pins for reversible connector capability.
