th
ese can be used to attach to front panel USB, auxiliary ports that mount in the
card slots, and also some devices that directly connect to the header.
USB 3.0 standard 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 Type-A (found on the I/O Hub) shares the power limit of USB 3.0 at
900ma @ 5V. Whereas USB 3.1 Type-C (also found on the IO Hub) has a
power limit of 3000ma (3A) @ 5V.
18. 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 the
same as the USB2 ports found on the motherboard’s hardwired I/O hub, but
these can be used to attach to front panel USB, auxiliary ports that mount in the
card slots, and also some 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 than this, it is
recommended to attach a powered USB Hub.
19. Backlit Audio Traces
Isolating audio traces reduces or eliminates electrical noise from the onboard
audio when running multiple devices at a very high frequency. The
combination of CPU and graphics card frequencies and/or SLI can cause static,
channel crosstalk, or other audio anomalies. Each channel’s traces are isolated
from other sources of electrical noise on the board, which improves sound
clarity. From there the traces are backlit to show the isolation path.
20. 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 cases
may have two headers on one cable strand: one labeled HD Audio, and one
labeled AC’97 – this header is not compatible with AC’97.
21. 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
