3. Setup Instructions
3.1. Package Contents
Verify that all components are present:
- Diymore 20/24 Pins ATX Power Supply Breakout Board
- Acrylic case panels (if 'With shell' option was selected)
- Screws and standoffs for assembly (if 'With shell' option was selected)
3.2. Acrylic Case Assembly (if applicable)
If your kit includes an acrylic case, follow these steps to assemble it:
- Carefully remove the protective film from both sides of the acrylic panels.
- Align the bottom acrylic panel with the standoff holes on the breakout board.
- Secure the board to the bottom panel using the provided screws and standoffs.
- Align the top acrylic panel and secure it with the remaining screws.
3.3. Connecting the ATX Power Supply
- Ensure your ATX power supply is unplugged from the mains power and switched off.
- Locate the main 20-pin or 24-pin ATX connector from your computer power supply.
- Carefully plug the ATX connector into the corresponding input port on the breakout board. Ensure it is fully seated.
- (Optional) If using external control, connect your single-chip microcomputer (5V) or external switch to the XH2.54-2P terminal.
4. Operating Instructions
4.1. Powering On/Off
- Plug your ATX power supply into the mains power.
- Flip the toggle switch on the breakout board to the 'ON' position. The voltage display will illuminate, showing the output voltage.
- To power off, flip the toggle switch to the 'OFF' position.
4.2. Understanding the Voltage Display and Outputs
The onboard voltage display provides real-time monitoring of the computer power supply's output voltage. The board offers the following voltage outputs via screw terminals:
- +12V
- -12V
- +5V
- 5VSB (Standby 5V)
- 3.3V
Connect your devices to the appropriate terminals, ensuring correct polarity.
4.3. USB Charging Outputs
The board features multiple USB ports for charging:
- 3 Standard USB Ports: Output DC5V, with a current range of 0.1A to 2.1A. Two blue indicator lights will illuminate when these ports have output.
- 1 Orange USB Port (Fast Charge): This port supports various fast charging protocols including Quick Charge 2.0/3.0/3.0+, FCP/SCP/HVSC, AFC, VOOC 2.0/4.0, PE, USB BC1.2 DCP, and 2.4A charging. The output voltage automatically adjusts between 5-12V, with an output current of 2A. Ensure your device and data cable support fast charging for optimal performance.
- 1 TYPE-C Interface: Supports PD2.0/PD3.0 protocols, offering output voltages of 5V or 9V, with an output current of 2A.
4.4. DC Female Connector
The DC female connector can be used in two ways:
- Output: Provides 12V output.
- Input: Can accept a DC input voltage between 12V-24V. When powered via this input, the mainboard's fast charge interface will have voltage output.
4.5. Adjusting VADJ Voltage
The board includes an adjustable potentiometer (labeled 'VADJ') which allows for fine-tuning of a specific voltage output. Refer to the board's markings and your specific application needs for adjustment.
5. Maintenance
To ensure the longevity and proper functioning of your breakout board:
- Keep the board clean and free from dust and debris. Use a soft, dry cloth for cleaning.
- Avoid exposing the board to moisture or extreme temperatures.
- Do not apply excessive force when connecting or disconnecting cables.
- Regularly check screw terminals for tightness to ensure good electrical contact.
6. Troubleshooting
6.1. No Power Output
- Ensure the ATX power supply is correctly connected and plugged into a working power outlet.
- Verify the toggle switch on the breakout board is in the 'ON' position.
- Check if the ATX power supply itself is functioning correctly (e.g., by testing it with a computer).
- Ensure the 20-pin or 24-pin connector is fully seated.
6.2. Incorrect Voltage Readings
- Confirm the ATX power supply is providing stable power.
- Ensure all connections are secure and free from shorts.
- If using the VADJ adjustment, ensure it is set correctly for your application.
6.3. USB Charging Issues
- Ensure the breakout board is powered on.
- Check if the blue indicator lights for the USB ports are illuminated.
- Verify your USB cable and device are functioning correctly.
- For fast charging, ensure both your device and cable support the relevant fast charge protocols.
