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.
