Familiarize yourself with the key components and connectors on your motherboard.


1.3 Component Installation
- CPU Installation:
Locate the AM4 CPU socket. Open the retention arm, align the triangular mark on your AMD Ryzen processor with the mark on the socket, and gently place the CPU into the socket. Close the retention arm to secure the CPU. Do not force the CPU into the socket.
- CPU Cooler Installation:
Install your CPU cooler according to its manufacturer's instructions. Ensure proper thermal paste application and secure mounting.
- Memory (RAM) Installation:
Open the clips on both ends of the DDR4 memory slots. Align the notch on the memory module with the key in the slot. Press down firmly on both ends of the module until the clips snap into place. For dual-channel performance, install modules in matching slots (refer to your specific motherboard manual for slot priority).
- Storage Device Installation (M.2 SSD):
Locate the M.2 slot(s). Remove the M.2 standoff screw. Insert the M.2 SSD at an angle into the slot, then gently push it down and secure it with the standoff screw.
- Graphics Card (GPU) Installation:
Open the retention clip on the primary PCIe x16 slot. Align your graphics card with the slot and press down firmly until it clicks into place. Secure the card to your PC case with a screw.
- Power Supply Connection:
Connect the 24-pin ATX power connector and the 8-pin (or 4+4-pin) CPU power connector from your power supply to the corresponding ports on the motherboard.
- Front Panel Connections:
Connect the front panel headers (Power Button, Reset Button, HDD LED, Power LED, USB ports, Audio jacks) to the corresponding pins on the motherboard. Refer to the motherboard diagram for correct pin assignments.
- Wi-Fi Antenna Installation:
Screw the included Wi-Fi antenna(s) onto the antenna connectors located on the rear I/O panel.
