2. Package Contents
Verify that your package contains the following items:
- TX550M Power Supply Unit
- Modular Cables (various types)
- 100mm Floppy Adapter
- AC Power Cord
- Mounting Screws (4 pcs)
- Pack of Zip-ties
- User Manual (this document)
- Case Badge
3. Setup and Installation
Before installation, ensure your computer system is powered off and disconnected from the main power outlet. Refer to your computer case manual for specific power supply mounting instructions.
- Mounting the Power Supply: Insert the TX550M power supply into the designated power supply bay in your computer case. Secure it using the four provided mounting screws. Ensure the fan faces the correct direction for optimal airflow, typically facing downwards if your case has a bottom vent, or upwards if it's a top-mounted PSU.
- Connecting Fixed Cables: Connect the fixed 24-pin ATX motherboard power cable and the 4+4-pin EPS/ATX12V CPU power cable to their respective ports on your motherboard.
- Connecting Modular Cables: Identify the necessary modular cables for your components (e.g., graphics card, SSDs, HDDs, optical drives). Plug these cables into the corresponding ports on the power supply unit and then connect them to your components. The semi-modular design allows for a cleaner build by only using the cables you need.

- Connect AC Power: Once all internal connections are secure, connect the AC power cord to the power supply's inlet and then to a wall outlet or surge protector.
- Power On: Ensure the power switch on the rear of the PSU is in the 'I' (On) position. You can now power on your computer system.
4. Operating Instructions
The CORSAIR TX550M is designed for continuous and reliable operation. Its 80 PLUS Gold certification ensures high energy efficiency, converting more wall power into usable electricity for your components and generating less waste heat.
- Power On/Off: Use the main power switch on the rear of the PSU to completely cut power to the unit. For normal operation, leave this switch in the 'I' (On) position and use your computer's system power button.
- Fan Operation: The 120mm rifle bearing fan operates quietly and adjusts its speed based on the power supply's temperature and load to maintain optimal cooling.

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your power supply.
- Dust Cleaning: Periodically inspect the power supply's fan and ventilation grilles for dust accumulation. Use compressed air to gently clear any dust, ensuring proper airflow. Always disconnect the power supply from the AC outlet before cleaning.
- Cable Management: Ensure cables are not obstructing airflow within your computer case. Good cable management contributes to better cooling for all components, including the PSU.
- Environmental Conditions: Operate the power supply in a well-ventilated environment, avoiding extreme temperatures or high humidity.
6. Troubleshooting
If you encounter issues with your CORSAIR TX550M power supply, consider the following troubleshooting steps:
- 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 rear of the PSU is in the 'I' (On) position.
- Verify that your wall outlet is functional by testing it with another device.
- System Instability/Random Reboots:
- Ensure all power cables (24-pin ATX, CPU, PCIe, SATA) are firmly seated in both the power supply and the respective components.
- Check for any loose connections or damaged cables.
- Confirm that your system's power requirements do not exceed the 550W capacity of the PSU.
- Unusual Noises:
- If you hear grinding or loud fan noises, ensure the PSU fan is not obstructed by cables or dust.
- If the noise persists, it may indicate a fan issue. Contact Corsair support.
If these steps do not resolve your issue, please refer to the Warranty and Support section for further assistance.
