This motherboard
provides a 4-Pin water
cooling CPU fan
connector. If you plan
to connect a 3-Pin CPU
water cooler fan, please
connect it to Pin 1-3.
This motherboard pro-
vides 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 two 8-pin ATX
12V power connectors. 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, pass-
words, and data. A TPM system
also helps enhance network
security, protects digital
identities, and ensures platform
integrity.
