Besides four default USB 2.0
ports on the I/O panel, there
are two USB 2.0 headers on
this motherboard. Each
USB 2.0 header can support
two USB 2.0 ports.
This motherboard supports
CASE OPEN detection feature
that detects if the chassis cover
has been removed. This feature
requires a chassis with chassis
intrusion detection design.
This is an interface for front
panel audio cable that allows
convenient connection and
control of audio devices.
This connector supports a
Trusted Platform Module (TPM)
system, which can
securely store keys, digital
certificates, passwords, and
data. A TPM system also helps
enhance network security,
protects digital identities, and
ensures platform integrity.
