4. Setup Guide
4.1. Physical Installation
Before installing any components, ensure your system is powered off and unplugged. Handle the motherboard by its edges to avoid static discharge.
- CPU Installation: Carefully open the AM5 socket lever. Align the triangular marker on your AMD Ryzen processor with the marker on the socket, then gently place the CPU into the socket. Close the lever to secure the CPU.
- RAM Installation: Open the clips on the DDR5 DIMM slots. Align the notch on your DDR5 memory modules 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, refer to your motherboard's specific manual for recommended slot population.
- M.2 SSD Installation: The NZXT N9 X870E features quick-release latches for M.2 SSDs. Locate the desired M.2 slot. Remove the M.2 heatsink cover. Insert your M.2 SSD into the slot at an angle, then gently push it down until it clicks into place with the quick-release latch. Reattach the heatsink cover.
- GPU Installation: Open the retention clip on the PCIe 5.0 x16 slot. Align your graphics card with the slot and press down firmly until it is fully seated and the retention clip locks. Secure the graphics card to your chassis with screws.
4.2. Power Connections
Connect the main 24-pin ATX power cable from your power supply to the motherboard. Connect the 8-pin (and optionally the second 8-pin) CPU power cable(s) to the corresponding headers at the top of the motherboard.
4.3. Front Panel and Rear I/O Connections
Connect your chassis's front panel cables (power button, reset button, USB, audio) to the appropriate headers on the motherboard. Refer to the detailed diagram in your physical user manual for exact pin layouts.
