Short 12 inch cable with black SATA 15 pin male plug and white Molex 4 pin female socket, 18AWG copper wires

EN-Labs 12 inch SATA 15 pin Male to Molex 4 pin LP4 Female Hard Drive Adapter

SKU CH-HMJY-YAW04

Converts a SATA 15-pin power connector to a Molex 4-pin LP4 female plug for IDE drives using 12-inch 18AWG copper cable

  • Powers IDE drives from a SATA supply
  • 12 inch cable reaches components easily
  • 18AWG copper conductors ensure reliable power delivery
  • 15 pin SATA male connects to standard PSU
  • 4 pin Molex female fits legacy hard drives

Purpose and audience

This adapter cable connects a SATA power supply to an IDE hard drive or other LP4 device. It is intended for builders or technicians who need to power older drives from a modern PSU.

Upgrade context

The cable replaces a missing or damaged Molex lead when a power supply only offers SATA connectors. The jump is worth it when legacy storage or optical drives must be reused without adding a Molex-equipped PSU.

Interface limits

The SATA 15 pin connector supplies 5 V and 12 V DC through 18 AWG copper conductors over a 12 inch run. Length and gauge set the practical voltage drop boundary for reliable device operation.

Questions about this item

How much clearance does the 12 inch cable need to reach from the SATA power port to the Molex LP4 connector?

The adapter spans 12 inches including both headers, so allow at least that much free space between your PSU SATA socket and the IDE drive Molex port.

Which way round do the 15 pin SATA male and 4 pin Molex female ends go, and what is the common mistake?

Plug the 15 pin SATA male end into the PSU and the 4 pin Molex female end onto the drive; the frequent error is reversing them, which leaves the drive unpowered.

Will the 18AWG copper conductors degrade and need replacement under normal desktop use?

The 18AWG copper wiring is rated for continuous 5 V and 12 V DC delivery and does not have a scheduled replacement interval in typical desktop operation.
