5. Setup and Installation
Follow these steps to properly install your ASHATA 90W DC-ATX Power Module:
- Prepare Your System: Ensure your computer system is powered off and disconnected from any power source.
- Mount the Module: Securely mount the ASHATA power module within your computer chassis, typically near the motherboard.
- Connect to Motherboard: Connect the main 20-pin ATX connector from the power module to the corresponding port on your motherboard.
- Connect Peripherals: Connect the 4-pin Molex and SATA power connectors to your storage drives (HDDs/SSDs) and other peripherals as required by your system.
- Connect AUX-12V: If your motherboard or specific components require it, connect the AUX-12V connector.
- Provide DC Input: Connect a stable 12V DC power source (external power adapter, not included) to the DC input port of the power module. Ensure the DC input cable is securely connected.
- Verify Connections: Double-check all connections to ensure they are firm and correctly seated.

6. Operating Instructions
Once the power module is correctly installed and all connections are secure:
- Connect your external 12V DC power adapter to a wall outlet.
- The system should power on automatically or can be powered on via the system's power button, depending on your motherboard's configuration.
- To power off the system, use the operating system's shutdown function or the system's power button.
7. Maintenance
The ASHATA 90W DC-ATX Power Module is designed for low maintenance. To ensure optimal performance and longevity:
- Keep Clean: Periodically inspect the module and surrounding area for dust accumulation. Use compressed air to gently remove dust.
- Ensure Airflow: Although fanless, adequate airflow within the chassis is important to dissipate heat. Ensure no obstructions block air circulation around the module.
- Avoid Overloading: Do not exceed the maximum 90W output power. Overloading can lead to instability or damage.
8. Troubleshooting
If you encounter issues with your power module, refer to the following troubleshooting tips:
- No Power to System:
- Verify that the external 12V DC power adapter is connected and receiving power from the wall outlet.
- Check all cable connections between the power module, motherboard, and peripherals for secure seating.
- Ensure the 12V DC input cable to the module is firmly connected.
- System Instability or Unexpected Shutdowns:
- Confirm that the total power consumption of your components does not exceed the module's 90W capacity.
- Check for proper ventilation within the chassis to prevent overheating.
- Verify that the input 12V DC power source is stable and provides sufficient current.
- Peripheral Devices Not Functioning:
- Ensure the 4-pin Molex and SATA power connectors are correctly attached to the respective devices.
- Check the power requirements of the peripheral devices.
