The DELOCK SATA cable, manufacturer's part number 84791, is an adapter cable designed to connect a Slimline-SATA device, such as an optical drive (e.g., CD or DVD burner), to a standard SATA port inside a computer. It enables both power and data transmission between a Slimline-SATA connector and a conventional SATA connector, as well as an internal power supply. The cable is specifically designed for use in computer enclosures where space-saving and compact designs are required.

Applications
This cable is used to connect Slimline-SATA devices—often found in slim form factors such as slim optical drives or certain hard drives—to standard SATA ports. These devices are commonly installed in notebooks, slim PCs, or compact desktop systems where available space is limited. The combination of data and power connections in a single cable reduces the number of required connections and simplifies installation.

Features and Specifications in Detail
One end of the cable features a 13-pin Slimline-SATA female connector, which connects to the Slimline device. The other end has a 7-pin SATA male connector, which plugs into a standard SATA data port on the motherboard or a SATA controller card. Additionally, a 4-pin power connector is integrated, which connects to the computer’s internal power supply to provide power to the device. The cable length is 70 cm, sufficient to connect most internal components within the enclosure without being too short or overly strained.

Technology Explained Simply
The Slimline-SATA standard is a more compact version of the conventional SATA connector, primarily used in optical drives and other compact devices. The 13-pin female connector handles both data transmission and power supply, with data transmission following the SATA specification. The DELOCK cable separates these functions: data transmission via the 7-pin SATA connector and power supply via the separate 4-pin power connector. This is necessary because standard SATA ports do not supply power—they only transmit data. The cable thus enables the use of Slimline devices in systems that lack Slimline-SATA ports.

Compatibility and Accessories
The cable is compatible with Slimline-SATA devices featuring a 13-pin connector, as well as with standard SATA ports on motherboards or SATA controller cards. It can be connected to internal power supplies equipped with 4-pin Molex connectors. No accessories are included in the package; the cable is supplied as a single unit. Available color variants—black and red—allow for visual differentiation during installation, especially in systems with multiple cables.

Installation and Mounting
Installation involves plugging the 13-pin Slimline-SATA connector into the device, the 7-pin SATA connector into the data port, and the 4-pin power connector into the power supply. The connection is mechanically stable and secured by the plug geometry. It is important to ensure the device is properly connected to avoid data loss or power failure. The cable is not intended for outdoor use, as no specific protection rating (e.g., IP67) is specified.

Operational Advantages
The cable reduces the number of required cables and connectors, as both data and power are transmitted via a single cable, with power supplied through the separate 4-pin connector. This simplifies installation and reduces cable clutter inside the enclosure. The 70 cm cable length offers sufficient flexibility for most standard PC enclosures. The black and red color variants facilitate identification during installation, especially in systems with multiple SATA cables.
