- M.2 SSD: Locate the M.2 slot(s). Insert the M.2 SSD at a slight angle, then gently push it down and secure it with the provided M.2 screw.
- SATA Drives: Connect SATA data cables from your storage drives (HDDs/SSDs) to the SATA ports on the motherboard. Connect power cables from your power supply to the drives.
Graphics Card 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 and the retention clip closes.
- Secure the graphics card to your PC case with screws.
- Connect any necessary PCIe power cables from your power supply to the graphics card.
2.3 Power and Front Panel Connections
Connect the power supply and front panel cables to the motherboard.
Power Connections:
- 24-Pin ATX Power: Connect the large 24-pin cable from your power supply to the main ATX power connector on the motherboard.
- CPU Power: Connect the 8-pin (or 4+4 pin) CPU power cable from your power supply to the CPU power connector near the CPU socket.
Front Panel Connections:
Connect the cables from your PC case's front panel (Power Button, Reset Button, HDD LED, Power LED, USB ports, Audio jacks) to the corresponding headers on the motherboard. Refer to the motherboard's silkscreen labels for correct pin alignment.

- Reseat the graphics card and RAM modules.
- If your CPU has integrated graphics, try removing the discrete GPU and connecting the monitor to the motherboard's video output.
- System Fails to Boot / Blue Screen Errors:
- Check RAM installation; try booting with one RAM stick at a time.
- Verify storage drive connections (SATA/M.2).
- Reset BIOS settings to default (usually an option in the BIOS or by clearing the CMOS battery).
- Peripheral Issues (USB, Audio, LAN):
- Ensure drivers are correctly installed.
- Check physical connections of peripherals.
- Verify settings in BIOS/UEFI.
