How to connect 4 HDDs to a PICO SPU which has only one 4 PIN Molex?

If you are working with a compact computer build or a mini-PC setup, you might find yourself limited by the number of connectors available on your power supply unit (PSU). A common scenario is having multiple hard disk drives (HDDs) that need power, but your Pico PSU (PICO SPU) only has one 4-pin Molex connector available. In this article, we'll explore how to connect four HDDs to a Pico PSU, while ensuring everything functions smoothly.

The Original Problem Code

The problem can be summarized as follows:

"I have 4 HDDs to power, but my Pico PSU only has a single 4-pin Molex connector. How can I connect all four HDDs?"

Solution Overview

To connect four HDDs to a Pico PSU with just one 4-pin Molex connector, you can use a Molex splitter cable. This method allows you to increase the number of devices powered through a single connector. Below, we’ll provide a detailed step-by-step process, as well as potential considerations to keep in mind.

Steps to Connect Multiple HDDs

Materials Required

  • 1x Molex Splitter Cable: This cable splits a single 4-pin Molex connector into two connectors.
  • 2x Additional Molex Splitter Cables: You will need these to further divide the two connections from the first splitter into four total connections.
  • 4x HDDs: Ensure that all your hard drives are compatible with a Molex power connection.

Step-by-Step Guide

  1. Power Off Your System: Always ensure your system is powered down and unplugged before making any hardware connections.

  2. Connect the First Splitter: Plug the single 4-pin Molex connector from your Pico PSU into one end of the Molex splitter cable.

  3. Connect Two HDDs: Connect the two outputs of the first splitter to two of your HDDs. Each HDD should be connected securely to ensure proper power flow.

  4. Add the Second Splitter: Take another Molex splitter cable and connect it to one of the remaining Molex outputs from the first splitter.

  5. Connect the Remaining Two HDDs: Use the outputs from the second splitter to connect the last two HDDs. Ensure that all cables are firmly attached.

  6. Power On Your System: Once all connections are secure, plug in your Pico PSU and power on your system.

Important Considerations

  • Power Limitations: Make sure that your Pico PSU can handle the total power requirements of all four HDDs. Check the specifications of the HDDs and the PSU to avoid overloading. Each standard 3.5" HDD typically uses around 10-15 watts.

  • Cooling: If you are adding multiple HDDs, consider the airflow and cooling of your case to prevent overheating.

  • Data Connections: While this guide focuses on power supply, remember that you'll also need to connect the data cables (SATA or IDE) from each HDD to your motherboard.

  • Monitoring: After setting everything up, monitor the HDDs for any operational issues or failures. Utilizing tools like CrystalDiskInfo can help track the health of your drives.

Conclusion

Connecting four HDDs to a Pico PSU with a single 4-pin Molex connector is possible with the use of splitter cables. This solution not only saves space but also helps maximize the utility of your PSU in a compact build. Always be mindful of the total power load and ensure proper cooling to maintain performance.
