How to Make a SATA Power Cable
(Zedcor Wholly Owned/ Images)

PATA and SATA hard drives use different power and data cables to connect to the computer. PATA, an older technology used for hard drives, requires a four-pin peripheral power cable to run. SATA hard drives, on the other hand, require a SATA power cable. Power supplies manufactured before 2003 did not include a SATA power cable. However, you can use an adaptor to convert an existing four-pin peripheral power cable to a SATA power cable, allowing you to upgrade nearly any hard disk to SATA.

Skill level:
Moderately Easy

  1. 1

    Shut down your computer and remove the power cable from the device panel located on the back of the computer.

  2. 2

    Remove any other cables attached to the device panel. Press the power button to drain the motherboard of electricity.

  3. 3

    Loosen the screws securing the cover to the case, or hold down the tabs on either side of the cover, and slide the cover off of the computer.

  4. 4

    Touch the chassis to ground yourself, or put on a grounding strap. Find the power supply and trace the cables coming from the component.

  5. 5

    Locate a four-pin peripheral power cable. The four-pin peripheral power cable has a white connector and four individual cables---two black, one red and one yellow---coming out the back.

  6. 6

    Remove your IDE-to-SATA power adaptor from its packaging. Connect the four-pin peripheral power connector at the end of the adaptor to other end of the four-pin peripheral power cable attached to your power supply.

  7. 7

    Connect the new SATA power cable to any of the SATA devices installed in your system.
