USB 3.2 Gen1 standard is 900ma @ 5V for unpowered devices. If your USB
device requires more power, it is recommended to attach a powered USB Hub.
USB 3.2 Gen2 Type-A (found on the I/O Hub) shares the power limit of USB
3.2 Gen1 at 900ma @ 5V.
Note: USB 3.2 Gen1 is more commonly referred to as USB 3.0.
23. USB 3.2 Gen2 Type-C Header
The USB 3.2 Gen2 header is used to connect additional USB interface plugs to
the motherboard; these headers are most often used to connect the
motherboard to the chassis to enable the USB 3.2 Gen2 ports on the chassis.
These will function similarly to the USB 3.2 Gen2 Type-C port sometimes
found on a motherboard’s rear I/O hub, but can also be used for the chassis’
front panel USB, auxiliary ports that mount in the card slots, and certain
devices that directly connect to the header. The USB 3.2 Gen2 Header on the
Z590 DARK is a shielded USB 3.2 Gen2 Header that supports up to 10Gb/s
with USB 3.2 Gen2.
This USB 3.2 Gen2 Header has a power limit of 3000ma (3A) @ 5V.
24. USB 2.0 Headers
The USB2.0 header is used to connect additional USB interface plugs to the
motherboard; these headers are most often used to connect the motherboard to
the chassis to enable the USB2.0 ports on the chassis. These will function
similarly to the USB2.0 ports found on the motherboard’s hardwired I/O hub,
but these can also be used for the chassis’ front panel USB, auxiliary ports that
mount in the card slots, and certain devices that directly connect to the header.
USB 2.0 standard is 500ma @ 5V per port (header total is 1000ma) for
unpowered devices. If your USB device requires more power, it is
recommended to attach a powered USB Hub.
25. Front Panel Audio Connector
This header is used to plug in the audio cable included with most PC chassis.
This connector is required for audio recording and/or playback via the audio
connectors on the chassis. This header uses the standard “HD Audio” jack.
Some chassis may provide two headers: one labeled HD Audio, and one labeled
AC’97; AC’97 cables are not compatible with this header on the Z590 DARK.
26. Front Panel Connectors
The Front Panel Connectors are the four main chassis connections. These
include the Power Switch, Power LED, Reset Switch, and HDD LED. The
Power and Reset switches are “Momentary Switches,” rather than “Latching
