Prepare power supply connector SATA 15-Pin is one of the standard peripheral power connectors in computers. It is the standard connector for all hard drives and SATA-based optical drives.
SATA power cables protrude from the power supply unit and are intended to be located only inside the computer case. This is in contrast to SATA data cables, which are also usually kept behind the case but can also be connected to external SATA (eSATA) devices such as external hard drives via a SATA to eSATA adapter.
Pinout power connector SATA 15-Pin
Pinout It is a reference that describes the pins or contacts that connect an electrical device or connector.
Below is the pinout for a standard SATA 15-Pin peripheral power connector according toATX Specifications (Version 2.2)If you use this pinout table to test the power supply voltage, be aware that the voltages must be within the specified tolerances for ATX.

Note: There are two less common types of SATA power connectors: a 6-pin connector called the Slim Connector (supplies +5 VDC) and a 9-pin connector called the Mini Connector (supplies +3.3 VDC and +5 VDC). The pinout tables for these connectors differ from the ones shown here.
More information about SATA cables and devices
SATA power cables are required to power internal SATA devices such as hard drives; they do not work with older Parallel ATA (PATA) devices. Because older devices that require a PATA connection still exist, some power supplies may only have 4-pin Molex connectors.
If your power supply doesn't provide a SATA power cable, you can purchase a Molex-to-SATA adapter to power your SATA device via a Molex power connection. Example: StarTech 4-pin to 15-pin Power Cable Adapter.
One difference between PATA and SATA data cables is that two PATA devices can be connected to the same data cable, while only one SATA device can be connected to a single SATA data cable. However, SATA cables are much thinner and easier to manage inside the computer, which is important for cable management and proper airflow.
While a SATA power cable has 15 pins, SATA data cables only have seven.
