The Intel 3.1 controller, known as the DSL6540 "Alpine Ridge" controller, provides USB 3.1 or Thunderbolt 3 depending on the implementation. The Intel USB 3.1 controller an expensive part, and is the a large part of the reason the Z170-Pro costs almost $40 more than the Z170-A. The implementation is using the Alpine Ridge controller for USB 3.1, and ASUS adds an EtronTech EJ179V for USB Power Delivery 2.0 and USB 3.1 Type-C switch capabilities. ASUS is also using the integrated MAC along with the Intel i219v PHY for the 1Gbit NIC.

The audio area is another area where the Z170-Pro is dubbed superior to the Z170-A. You cannot see it, but the Z170-Pro uses an ALC1150 while the Z170-A used the ACL892. The ALC1150 is a superior audio codec, and much newer. ASUS provides the audio circuit with some Nichicon Gold series audio capacitors and a Texas Instruments R458012 amplifier for the front panel output. For better BLCK overclocking margins, ASUS uses the IDT 6V4153NLG.

A 128Mbit (16MB) BIOS ROM sits in a DIP socket for easy replacement, and a TPU EC provides expanded fan control and temperature monitoring. The ASMedia ASM1442K is a level shifter that converts digital video into HDMI.

The nuvoTon NCT6793D is the main Super IO, and it does most of the basic system monitoring. These four ASMedia ASM1480 are quick switches and together switch 8x PCI-E 3.0 between the first and second PCI-E 16x slots.
