Solved Sata power extention cable - wiring question Tags: sata power SATA extension cable Storage Last response: November 18, 2013 12:07 PM in Storage Share stx123 November 17, 2013 2:15:03 PM I have a power supply that has the 5 wire sata power cable (orange,black,red,black,yellow) and I bought a sata power extension cable on ebay that only has 4 wires (black,red,black,yellow) So my question is, is it ok to plug the 4 wire extension cable to the 5 wire power cable and then into a hard drive?

The drive can operate with only the 5V (logic board), 12V (drive motor), and Ground wires connected. Very few (if any) drives actually use the 3.3V wires anyway.

Share giantbucket a b G Storage November 17, 2013 5:43:49 PM from what i know, HDD (and probably CD/DVD) use 12V and 5V, and SSD use just 5V. so the orange 3.3V is currently irrelevant. m 0 l Can't find your answer ?

I thought I bought a faulty connector at first since it was sent from china but the wires seem to be in the correct order. Better safe than sorry thanks for the input m 0 l Can't find your answer ?
