Pin Atx Power; Securing The Motherboard Into The Chassis; Power Connections - EVGA 112-CK-NF72-K1 Installation Manual

Determine if it would be easier to make all the connections prior to this step or to secure the
motherboard and then make all the connections.
Use the following procedure to install the I/O shield and secure the motherboard into the
chassis.
Note:
Be sure that the CPU fan assembly has enough clearance for the chassis covers to lock
into place and for the expansion cards. Also make sure the CPU Fan assembly is aligned
with the vents on the covers.
Installing the I/O Shield
The motherboard kit comes with an I/O shield that is used to block radio frequency
transmissions, protects internal components from dust, foreign objects, and promotes
correct airflow within the chassis.
Before installing the motherboard, install the I/O shield from the inside of the chassis. Press
the I/O shield into place and make sure it fits securely. If the I/O shield does not fit into
the chassis, you would need to obtain the proper size from the chassis supplier.

Securing the Motherboard into the Chassis

Most computer chassis have a base with mounting studs or spacers to allow the
motherboard to be secured to the chassis and help to prevent short circuits. If there are
studs that do not align with a mounting hole on the motherboard, it is recommended that
you remove that stud to prevent the possibility of a short circuit.
1. Carefully place the motherboard onto the studs/spacers located inside the chassis.
2. Align the mounting holes with the studs/spacers.
3. Align the connectors to the I/O shield.
4. Ensure that the fan assembly is aligned with the chassis vents according to the fan
assembly instruction.
5. Secure the motherboard with a minimum of six screws.

Power Connections

This motherboard requires an ATX power supply. Make sure your power supply can
provide enough wattage to power all the components you will be installing.

24-pin ATX Power

PWR1 is the main power supply connector located along the edge of the board next to the
DIMM slots. Make sure that the power supply cable and pins are properly aligned with the
connector on the motherboard. Firmly plug the power supply cable into the connector and
make sure it is secure.
