Introduction
This manual provides instructions for the installation, operation, and maintenance of the OCESTORE ATX-Switch02 160W Pico PSU. This compact power supply unit is designed for Mini ITX and 1U computer cases, offering a fanless, silent operation with a maximum output of 160W. It requires an external 12V DC power adapter for operation.
Safety Information
- Ensure the power adapter used meets the specified voltage and current requirements (12V DC, minimum 12.5A). Using an underpowered adapter may lead to system instability or damage.
- Do not expose the unit to moisture or extreme temperatures.
- Handle with care to avoid damage to electronic components.
- Disconnect all power sources before installation or maintenance.
Package Contents
Verify that all components are present in the package:
- 1 x OCESTORE ATX-Switch02 160W Pico PSU Module
- 1 x ATX Power Switch Cable (DC input cable)
- Additional power cables (e.g., SATA power connectors)

Setup
Follow these steps to install the Pico PSU:
- Prepare the Motherboard: Ensure your motherboard is compatible with a 24-pin ATX power connector.
- Connect the Pico PSU: Carefully align and firmly connect the 24-pin ATX connector of the Pico PSU module to the corresponding 24-pin power socket on your motherboard.
- Connect Peripheral Power: If your system requires additional power for drives (e.g., SATA SSDs/HDDs), connect the provided SATA power cables from the Pico PSU to your devices.
- Connect DC Input: Connect the DC input cable to the Pico PSU module. Then, connect the other end of this cable to a compatible 12V DC power adapter (not included). The power adapter must provide at least 12.5A to ensure stable operation for the 160W output.
- Secure Components: Ensure all connections are secure and components are properly mounted within your computer case.

Operating
Once the Pico PSU is correctly installed and connected to a suitable 12V DC power adapter, your system is ready for operation.
- Power On: Apply power to the external 12V DC adapter. The system should power on according to your motherboard's power settings (e.g., via the case's power button).
- Fanless Operation: The OCESTORE ATX-Switch02 operates silently as it is designed without a fan. This is normal and indicates proper functioning.
- Power Off: Shut down your system through the operating system. The Pico PSU will cease providing power once the motherboard signals a shutdown.
Maintenance
The OCESTORE ATX-Switch02 Pico PSU requires minimal maintenance due to its fanless design and robust construction.
- Cleaning: Periodically inspect the unit for dust accumulation. If necessary, gently clean with a soft, dry brush or compressed air while the system is powered off and disconnected from the power source.
- Environment: Ensure the operating environment is free from excessive dust, moisture, and extreme temperatures to prolong the lifespan of the unit.
Troubleshooting
If you encounter issues with your Pico PSU, consider the following:
- No Power:
- Verify that the external 12V DC power adapter is correctly connected and functioning.
- Ensure the power adapter provides sufficient current (minimum 12.5A for 160W output). An underpowered adapter can prevent the system from booting or cause instability.
- Check all cable connections, especially the 24-pin ATX connector to the motherboard and the DC input cable to the Pico PSU.
- System Instability or Shutdowns:
- This often indicates insufficient power. Confirm your external 12V DC power adapter meets the 12.5A current requirement.
- Ensure the total power draw of your components (CPU, motherboard, drives, etc.) does not exceed the 160W capacity of the Pico PSU.
- Drives Not Spinning Up:
- Verify that the SATA power connectors are firmly attached to your drives.
- Confirm the external power adapter provides enough current to power all connected devices. High-power HDDs may require more current than lower-power SSDs.
