SATA data vs SATA power

SATA data and SATA power are separate connectors with different roles and contact counts. Sharing the SATA name does not make them substitutes.

Computer-generated illustration, not a photograph. — P029 · ConnectorSATA 7-pin data connector

How they differ

SATA 7-pin data connector Look for the narrow, keyed data connection. Read the device service guidance before opening equipment; the atlas provides recognition, not a repair procedure.
SATA 15-pin power connector Count the wider power section separately from the seven-position data section and read the drive/backplane documentation.
