12V 8-pin CPU Power Connectors
JPWR1 and JPWR2 are the 8-pin 12V DC power input for the CPU or alternative single
power source for a special enclosure when the 24-pin ATX power is not in use. Refer to the
table below for pin definitions.
4.2 Headers and Connectors
Fan Headers
There are six fan headers on the motherboard. These are 4-pin fan headers; pins 1-3 are
backward compatible with traditional 3-pin fans. The onboard fan speeds are controlled by
Thermal Management via BIOS. When using the Thermal Management setting, please use
all 3-pin fans or all 4-pin fans.
TPM Header
The JTPM1 header is used to connect a Trusted Platform Module (TPM)/Port 80, which is
available from a third-party vendor. A TPM/Port 80 connector is a security device that supports
encryption and authentication in hard drives. It allows the motherboard to deny access if the
TPM associated with the hard drive is not installed in the system. See the table below for
pin definitions.
