5. Installation Guide

5.1 CPU Installation

1. Open the CPU socket lever and remove the protective cover.
2. Carefully align the CPU with the socket, ensuring the triangular mark on the CPU matches the mark on the socket.
3. Gently place the CPU into the socket without forcing it.
4. Close the socket lever to secure the CPU.

5.2 Memory (RAM) Installation

1. Open the clips at both ends of the DDR5 DIMM slots.
2. Align the notch on the DDR5 memory module with the key on the DIMM slot.
3. Insert the memory module firmly into the slot until the clips snap into place.
4. For dual-channel operation, install modules in matching color slots (e.g., A2 and B2).

5.3 Storage (M.2 SSDs, SATA Drives) Installation

• M.2 SSD: Remove the M.2 Thermal Guard. Insert the M.2 SSD into the slot at an angle, then push it down and secure it with the EZ-Latch mechanism or screw. Reattach the Thermal Guard.
• SATA Drives: Connect one end of the SATA data cable to a SATA port on the motherboard and the other end to your SATA storage device. Connect a SATA power cable from your power supply to the device.

5.4 Expansion Card (PCIe) Installation

1. Align your PCIe expansion card (e.g., graphics card) with the desired PCIe slot.
2. Press down firmly until the card is seated correctly and the retention clip locks.
3. Secure the card to the chassis with a screw.

5.5 Power Supply Connections

• Connect the 24-pin ATX main power connector from your power supply to the motherboard.
• Connect the 8-pin (or 4+4-pin) ATX 12V CPU power connector to the motherboard.

5.6 Front Panel Connections

Connect the cables from your PC case's front panel (power button, reset button, USB ports, audio jacks, LED indicators) to the corresponding headers on the motherboard. Refer to the motherboard diagram for exact header locations.
