The SATA 15 pin power supply connector is one of the standard peripheral power connectors in computers today.

This power connector is the standard connector for all SATA based hard drives and optical drives.

Below is the pinout for the standard SATA 15 pin peripheral power connector as of Version 2.2 of the ATX Specification (PDF).

Note: There also exists two less common SATA power connectors: a 6 pin connector called a slimline connector (supplies +5 VDC) and also a 9 pin connector called a micro connector (supplies +3.3 VDC and +5 VDC). The pinout tables for those connectors differ from the one below.

Note: If you're using this pinout table to test power supply voltages, be aware that the voltages must be within ATX specified tolerances.

You can see other ATX power supply connector pinouts in my ATX Power Supply Pinout Tables list.
