What are SATA pins?
The SATA 15-pin power supply connector is one of the standard peripheral power connectors in computers. It’s the standard connector for all SATA-based hard drives and optical drives. SATA power cables protrude from the power supply unit and are meant to reside only inside the computer case.
Do SATA hard drives have jumpers?
Some SATA drives have a jumper but it’s only used to force a newer drive to run slower. SATA speeds have changed from 1.5 to 3.0 and now to 6 Gigabits per second.
Is Molex to SATA safe?
Molex to SATA adapter cables are a very simple and cost-effective alternative to buying a new power supply. However, they can be a dangerous alternative to getting a quality power supply, potentially damaging your SSD, internal components, and may also pose a fire risk in your home.
What is a SATA connector?
The Serial ATA or SATA connector is used as an interface for connecting a host bus adapter to a mass storage device or optical drive. This connector was designed to replace the older connectors, 34-pin, 40-pin, etc. This connection is sometimes referred to as the SATA “L” due to the shape of the connector.

Do you need a jumper pin on a SATA drive?
You don’t need a jumper pin on your SATA drive for desktops or servers manufactured after 2002. For older equipment, you can use a jumper on the pins to limit its data transfer rate so it can work smoothly with older, slower drives. A jumper pin is a rectangular connector that creates a circuit between two pins.
