This motherboard provides a
24-pin ATX power connector.
To use a 20-pin ATX power
supply, please plug it along
Pin 1 and Pin 13.
This motherboard provides
a 8-pin ATX 12V power con-
nector. To use a 4-pin ATX
power supply, please plug it
along Pin 1 and Pin 5.
*Warning: Please make
sure that the power cable
connected is for the CPU
and not the graphics card.
Do not plug the PCIe power
cable to this
connector.
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.
This COM header supports
serial port module.
