panel USB, auxiliary ports that mount in the card slots, and also some devices
that directly connect to the header.
USB 3.1 Gen 1 standard available current is 900mA @ 5V for unpowered
devices. If your USB device requires more power than this, it is recommended
to attach a powered USB Hub.
USB 3.1 Gen 2 Type-A (found on the I/O Hub) shares the power limit of USB
3.1 Gen 1 at 900mA @ 5V.
14. 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 both designed to use "Momentary Switches,"
rather than "Latching Switches," which means the connection between the two
posts needs to be made just briefly for it to work, as opposed to being held in
place. This is why the Power and Reset switches can be triggered with a screw
driver by simultaneously touching the + and - posts.
Power LED will power on with the system, indicating the system is on and can
blink with CPU activity.
HDD LED will blink during access to the SATA ports. M.2 SSDs will also
activate this LED.
15. CMOS Battery
The +3V CMOS battery backup provides uninterruptable power to the
BIOS/UEFI to keep all of the settings; otherwise, each boot would behave like
you just reset the BIOS. These batteries typically last several years and rarely
need to be replaced.
16. Front Panel Audio Connector
This is a motherboard header, which is used to plug in the audio cable
originating from most PC chassis to allow audio to be recorded from or played
through the audio connectors on the chassis. This header has a connector that
looks similar to USB2 and will use the standard "HD Audio" jack. Some
systems may have two headers: one labeled HD Audio, and one labeled AC'97
– this header is not compatible with AC'97.
17. USB 3.1 Header
The USB 3.1 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 USB3.1 ports on the chassis. These will function
similarly to the USB3.1 Type-C port found on the motherboard's rear I/O
