Safety Precautions
- Ensure the power supply is disconnected from the AC power outlet before installation or maintenance.
- Do not open the power supply unit. High voltages are present inside, and opening the unit will void the warranty.
- Install the power supply in a well-ventilated area.
- Use only the cables provided with the power supply.
- Do not overload, abuse, or modify the power supply unit.
- This unit is designed for personal computer use. Use for cryptocurrency mining purposes is not covered by warranty and may shorten the life of the unit.
Setup and Installation
Follow these steps to properly install your power supply unit into your computer system.
- Prepare Your System: Ensure your computer case is compatible with ATX form factor power supplies. Turn off and unplug your computer from the wall outlet.
- Mount the Power Supply: Insert the power supply into the designated bay in your computer case. Secure it with screws provided with your case or power supply.
- Connect Main Power Cables: The 20/24-pin Main Power connector and the 4+4-pin 12V CPU power connector are permanently attached. Connect these to their respective ports on your motherboard.
- Connect Modular Cables: Identify the necessary modular cables for your components (e.g., graphics card, storage drives).
- PCI Express (PCIe): Use the 6+2-pin PCIe connectors for your graphics card(s). The power supply includes two such connectors.
- SATA: Connect SATA power cables to your SSDs, HDDs, and optical drives. The power supply includes four SATA connectors.
- Peripheral (Molex): Use Peripheral connectors for older components or case fans. The power supply includes four Peripheral connectors.
- Floppy: A single Floppy connector is provided for legacy devices.
- Cable Management: Route cables neatly to ensure proper airflow and a clean build.
- Voltage Selection: On the rear of the power supply, ensure the 115/230V switch is set to the correct voltage for your region. Incorrect voltage selection can damage the unit and connected components.
- Final Check: Double-check all connections to ensure they are secure.

Operating Instructions
Once installed, operating your power supply is straightforward.
- Power On: Connect the AC power cord to the power supply and a wall outlet. Flip the main power switch on the rear of the PSU to the 'ON' position.
- System Startup: Power on your computer system via the case's power button.
- Fan Operation: The 120mm black fan is auto-thermally controlled, meaning its speed adjusts automatically based on the power supply's temperature to maintain optimal cooling and minimize noise.
Maintenance
Regular maintenance helps ensure the longevity and performance of your power supply.
- Dust Removal: Periodically clean the exterior of the power supply and the fan grille to prevent dust buildup, which can impede airflow and cooling. Use compressed air or a soft brush. Ensure the unit is powered off and unplugged before cleaning.
- Airflow: Ensure that the power supply's intake and exhaust vents are not obstructed by cables or other components within the computer case. Proper airflow is crucial for efficient cooling.
Troubleshooting
If you encounter issues with your power supply, consider the following common troubleshooting steps:
- No Power:
- Check if the AC power cord is securely connected to both the power supply and the wall outlet.
- Ensure the main power switch on the PSU is in the 'ON' position.
- Verify the 115/230V switch is set correctly for your region.
- Test the wall outlet with another device to confirm it has power.
- System Instability/Random Shutdowns:
- Ensure all power connectors (20/24-pin, 4+4-pin CPU, PCIe, SATA) are firmly seated.
- Confirm that your system's power requirements do not exceed the 700W capacity of the power supply.
- Check for proper ventilation within your case to prevent overheating of components, including the PSU.
- Unusual Noises:
- A slight fan noise is normal during operation, especially under load. If the noise is excessive or unusual, ensure no cables are obstructing the fan.
- If the fan is not spinning, and the system is under load, it may indicate a fan issue or a protection mechanism.
- Built-in Protections: This power supply includes heavy-duty protections such as Short-Circuit Protection (SCP), Over-Current Protection (OCP), Over-Voltage Protection (OVP), Over-Power Protection (OPP), Under-Voltage Protection (UVP), and Over-Temperature Protection (OTP). If the unit shuts down unexpectedly, these protections may have been triggered to safeguard your components. Disconnect power, wait a few minutes, and re-attempt startup after checking for any issues.
