Carefully position the motherboard above the standoffs, aligning the

screw holes on the motherboard with the standoffs and the I/O shield with

the case opening.

     Gently lower the motherboard onto the standoffs, ensuring it rests

evenly.

     Secure the Motherboard:

     Once the motherboard is properly positioned, use screws to secure it to

the standoffs.

     Insert the screws through the motherboard's screw holes and tighten

them firmly but not excessively. Be cautious not to overtighten and

damage the motherboard.

     Connect Power Supply Cables:

     Locate the main power connector (usually a large, rectangular

connector) from the power supply.

     Connect it to the corresponding motherboard power socket, typically

located near the CPU.

     Ensure the connector is properly aligned and firmly inserted, applying

gentle pressure until it clicks into place.

     Connect Other Cables:

     Connect the necessary cables from the power supply to the

motherboard, including the CPU power connector, SATA power

connectors, and any additional connectors required by your specific

motherboard and components.

     Refer to the motherboard and component manuals for specific cable

connections.

     Connect Front Panel Cables:

     Connect the front panel cables, including the power switch, reset

switch, HDD LED, power LED, and any other front panel connectors.

     Consult the motherboard manual for the specific pin layout and

connector orientation.
