This motherboard provides
an 8-pin ATX 12V power
connector. To use a 4-pin
ATX power supply, please
plug it along Pin 1 and Pin
5.
This COM1 header
supports a serial port
module.
This connector supports SPI
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.
Please connect a
Thunderbolt™ add-in card
(AIC) to this connector
via the GPIO cable.
*Please install the Thunderbolt™
AIC card to PCIE3 (default slot).
RGB headers are used to connect
RGB LED extension cables which
allow users to choose from
various LED lighting effects.
Caution: Never install the
RGB LED cable in the wrong
orientation; otherwise, the cable
may be damaged.
*Please refer to page 34 for further
instructions on this header.
