5. Setup and Installation

Follow these steps to install your Mars Gaming MPB850 power supply:

1. Prepare Your System: Ensure your computer is completely powered off and unplugged from the wall outlet. Open your PC case.
2. Remove Old PSU (if applicable): Disconnect all cables from your old power supply and remove its mounting screws. Carefully slide it out of the case.
3. Install New PSU: Gently slide the Mars Gaming MPB850 into the power supply bay of your PC case. Ensure the fan is facing the correct direction for optimal airflow (usually facing downwards if your case has a bottom vent, or upwards if it's a top-mounted PSU). Secure the power supply with the provided mounting screws.
4. Connect Main Power (20+4 Pin): Connect the large 20+4 pin ATX connector to the corresponding port on your motherboard. Ensure it clicks into place.
5. Connect CPU Power (4+4 Pin): Connect the 4+4 pin CPU power connector to the CPU power port on your motherboard. This is usually located near the CPU socket.
6. Connect PCI-E Power (6+2 Pin): If you have a dedicated graphics card, connect the 6+2 pin PCI-E connectors to your graphics card. Some high-end cards may require two or more such connectors.
7. Connect SATA Devices: Use the SATA power connectors for your SSDs, HDDs, and optical drives.
8. Connect PATA Devices: Use the PATA (Molex) connectors for older devices or case fans that require them.
9. Cable Management: Utilize the flat, black, and extra-long cables to route them neatly behind the motherboard tray or through designated channels in your case. This improves airflow and aesthetics.
10. Close Case and Connect AC Power: Once all connections are secure, close your PC case. Connect the AC power cord to the power supply and then to a wall outlet.

6. Operating Instructions

After successful installation, operating the Mars Gaming MPB850 is straightforward:

1. Power On: Ensure the power switch on the back of the power supply is in the 'ON' (I) position.
2. Start PC: Press the power button on your computer case. The power supply will provide power to all connected components.
3. Fan Operation: The 120mm fan will operate quietly, utilizing SilentRPM technology to adjust its speed based on the power supply's load and temperature, ensuring optimal cooling with minimal noise.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your power supply:

• Dust Cleaning: Periodically clean dust from the power supply's fan and vents using compressed air. Ensure the PC is powered off and unplugged before cleaning.
• Airflow: Ensure that the PC case has adequate airflow and that the power supply's intake and exhaust vents are not obstructed.
• Do Not Open: Never attempt to open the power supply unit. It contains high voltage components that can cause severe injury or death. Opening the unit will also void the warranty.

8. Troubleshooting

If you encounter issues with your Mars Gaming MPB850, consider the following:

• No Power:
  • Check if the AC power cord is securely connected to both the power supply and the wall outlet.
  • Ensure the power switch on the back of the PSU is in the 'ON' (I) position.
  • Verify that all internal power cables (20+4 pin, 4+4 pin, PCI-E) are correctly and firmly connected to the motherboard and components.
  • Test the wall outlet with another device to confirm it has power.
• Intermittent Power/System Instability:
  • Ensure the power supply is adequately rated for all your system components.
  • Check for loose cable connections.
  • Ensure proper ventilation to prevent overheating.
• Unusual Noise:
  • While the SilentRPM fan is designed for quiet operation, excessive noise might indicate dust buildup. Refer to the Maintenance section for cleaning.
  • If the noise persists and is not related to dust, contact customer support.

If these steps do not resolve the issue, contact Mars Gaming customer support for further assistance.
