- M/B (Motherboard): Connect the 24-pin ATX cable to the motherboard.
- CPU/PCI-E: Connect the 8-pin (4+4) CPU cable to the motherboard's CPU power connector. Connect 6+2-pin PCIe cables to your graphics card(s) as needed.
- 12V-2x6: Connect the 16-pin PCIe 5.1 cable directly to compatible graphics cards.
- Peripheral-IDE/SATA/Molex: Connect SATA power cables to storage drives (HDDs, SSDs) and optical drives. Use Molex cables for other peripherals if required.
4.4. Connect to Components
Route the connected modular cables neatly within your case and connect them to their respective components (motherboard, CPU, graphics card, storage drives, etc.). Ensure all connections are secure.
4.5. Connect AC Power
- Ensure the power switch on the back of the power supply is in the 'OFF' (0) position.
- Connect the AC power cord to the power supply's AC inlet.
- Plug the other end of the AC power cord into a grounded wall outlet or surge protector.
5. Operation
Once installation is complete, you can power on your system.
5.1. Powering On/Off
- Flip the power switch on the back of the power supply to the 'ON' (I) position.
- Press the power button on your computer case.
- To turn off the system, shut down your operating system normally. For a complete power cycle, flip the power switch on the PSU to 'OFF' (0) after system shutdown.
6. Maintenance
Proper maintenance helps ensure the longevity and optimal performance of your power supply.
6.1. Cleaning
- Periodically clean the exterior of the power supply and its fan grille to prevent dust buildup.
- Use compressed air to gently remove dust from the fan and vents.
- Always disconnect the AC power cord before cleaning.
6.2. Fan Check
Ensure the power supply fan is operating correctly. If you notice unusual noises or the fan is not spinning under load, consult the troubleshooting section or contact support.
7. Troubleshooting
If you encounter issues with your power supply, refer to the following common problems and solutions.
7.1. No Power
- Check AC Power: Ensure the AC power cord is securely connected to both the power supply and the wall outlet. Verify the wall outlet has power.
- PSU Switch: Confirm the power switch on the back of the PSU is in the 'ON' (I) position.
- Cable Connections: Double-check all modular cable connections, especially the 24-pin ATX and 8-pin CPU cables, are firmly seated.
- System Components: Disconnect non-essential components (e.g., extra drives, peripherals) to isolate if a faulty component is preventing the system from booting.
7.2. System Instability or Random Shutdowns
- Overload: Ensure your system's power requirements do not exceed the 750W capacity of the PSU.
- Ventilation: Check that the power supply and case have adequate airflow and are not obstructed by dust.
- Cable Integrity: Verify all power cables are in good condition and properly connected.
- Component Issues: Test other components (RAM, GPU) if possible, as instability may not always be PSU-related.
