SUMMARY

The polarity of the HDD LED cable for motherboard connection is crucial for proper functionality. In this discussion, it is established that the white wire typically serves as the ground (negative), while the blue wire is the positive connection. Users are advised to check the connector for polarity markings. If the LED does not illuminate, reversing the connector is a safe troubleshooting step.

PREREQUISITES
  • Basic understanding of motherboard pin connections
  • Familiarity with LED wiring conventions
  • Knowledge of electrical polarity
  • Experience with computer hardware assembly
NEXT STEPS
  • Research motherboard manuals for specific pin configurations
  • Learn about LED wiring standards in PC components
  • Explore troubleshooting techniques for non-functioning LEDs
  • Investigate the implications of incorrect wiring on hardware performance
USEFUL FOR

This discussion is beneficial for PC builders, hardware enthusiasts, and anyone involved in assembling or troubleshooting computer systems, particularly those working with motherboard connections and LED indicators.

I am connecting my towers power wires to the motherboard.

The motherboard tells me how to connect the. Hdd led cable. And were the pluss and minus wires go.

But the. Hdd led cable is mad of a. Blue and white wire.

Witch one is the pluss. And. Negitive?

The white wire is customarily the ground wire [negative]. If you look closely at the connector, it is likely marked showing the polarity. It is unlikely you will fry anything if you have it reversed. If the led light doesn't work, reverse the connector and try again.
