On Board Peripherals
The Intel H170 chipset is a single-chip solution, which is also known as a PCH (Platform Controller Hub). This chip has six SATA-600 ports, supporting RAID (0, 1, 10, and 5). One of those ports is available on the M.2 slot, and four are installed on the motherboard edge and rotated 90°, so the installation of video cards will not block them.
Notice that the SATA-600 ports are grouped in pairs, and each pair can be used as a SATA Express port.
The Intel H170 chipset supports six USB 2.0 ports and eight USB 3.0 ports. The Gigabyte H170N-WIFI offers two USB 2.0 ports, available through a header located on the motherboard. There are seven USB 3.0 ports, all of them controlled by the chipset, being five of them at the rear panel (one of them being Type C), and two available through one header.
The Gigabyte H170N-WIFI does not support FireWire or Thunderbolt ports.
This motherboard supports 7.1 audio format, i.e., eight channels. On this motherboard, the audio is generated by the chipset using the Realtek ALC1150 codec, which is an excellent audio codec, providing 115 dB signal-to-noise ratio for the analog outputs, 104 dB signal-to-noise ratio for the analog inputs, and up to 192 kHz sampling rate for both inputs and outputs, with 24-bit resolution. These specifications are good even for the user who wants to work professionally by capturing and editing analog audio.
The analog audio connections are independent if you use up to 5.1 analog speakers, and there is an optical SPDIF output on the rear panel. There is a connector where you can install an SPDIF coaxial output.
The portrayed motherboard has two Gigabit Ethernet ports, one controlled by an Intel I219V chip and the other one controlled by an Intel I211AT chip.
In Figure 8, you can see the motherboard rear panel with a shared PS/2 keyboard/mouse connector, two USB 3.0 Type A ports ports, the connectors for the Wi-Fi antennas, DVI-D output, two HDMI outputs, one USB 3.0 Type C ports, two more USB 3.0 Type A ports, two Gigabit Ethernet ports, optical SPDIF output, and the analog audio jacks.
