Our take on the Rocstor 3 Slimline SATA 3.0 to SATA 3.0 LP4 Adapter Cable

This is a short adapter cable that connects a slimline SATA optical drive to a standard SATA port and a Molex LP4 power lead. It carries data on one SATA connector and power on the smaller slimline connector, so a laptop-style DVD or Blu-ray drive can run in a desktop build. It suits people fitting a slim optical drive into a tower case or replacing a failed drive cable. It is a passive part with no chips, so it does the same job as other slimline SATA adapters; the differences come down to connector fit and cable length.

Questions and answers

What does this cable connect?
It links a slimline SATA optical drive to a motherboard SATA port and a Molex LP4 power plug. The small combined connector goes to the drive; the two larger ends go to the board and PSU.
Will it work with a regular 3.5-inch hard drive?
No. Full-size drives use a separate wide SATA data and SATA power connector. This cable is for slimline drives such as laptop DVD and Blu-ray units.
Do I need a Molex LP4 plug on my power supply?
Yes. The power side is a 4-pin Molex LP4. If your PSU only has SATA power leads, you need a SATA-to-LP4 adapter.
Does it need any software or drivers?
No. It is a passive cable. The drive appears as a normal SATA device once both ends are connected.
Can I use it for an external enclosure?
Only if the enclosure accepts a slimline SATA drive and provides its own power. This cable is meant for internal connections.
