SATA Power Supply – Everything you Need to Know

by seo bhartirohila

Serial ATA or SATA cables are used to attach devices in computer cable assemblies, like storage devices. This technology is itself a connector interface mainly used for connections in storage applications in which the cables are utilized to attach a mass storage device to a host bus adapter like a motherboard.

SATA stands for Serial Advanced Technology Attachment, which is an IDE (integrated development environment) standard. In modern computers, this interface is used to transfer information at high rates through compact cables. In this post, we are going to discuss what is SATA Power Supply, its uses, and what are its types?

The cables can attach to a range of devices, counting:

How to Install a SATA Power Supply 

The installation of the SATA power supply is not a complicated task, but it is necessary to finish the installation correctly and safely. The method or procedure will differ depending on the purpose of the cable. If you are simply looking to replace a hard disk drive, you can avoid the requirement of disconnecting the SATA cable from the mainboard. So, this way, just the SATA power cable connected to the hard disk drive will need to be replaced and removed.

Contrary to that, if you have a SATA cable to add extra storage, you are not required to address the existing drive. In its place, you will require the following steps:

  • Keeping the space between the existing and new drives, insert the new hard disk drive into the unfilled bay in your system’s case.
  • Make sure that the SATA connection ports are simply accessible
  • Attach the cable with the port on a hard drive and join the other end to the motherboard
  • The main drive should be attached to the board’s lowest SATA port – typically SATA 1 or SATA 0
  • Then finish the process by making sure that all connections are protected, closing the PC case, powering the computer once it is safe to do so
  • Maybe, it is necessary to format the innovative hard drive or possibly reinstall the OS, and it depends on the specifications of your application

PATA vs. SATA Cables

SATA power cables provide faster info/data transfer compared to their predecessors. Initially introduced in 2001, they are way better than older cables. Following is some information for different SATA interfaces

Bandwidth Throughput Interface Gb/s SATA Interface
600MB/s 6Gb/s SATA III
300MB/s 3Gb/s SATA II
150MB/s 1.5Gb/s SATA I


As opposed to SATA Power Supply, PATA (Parallel Advanced Technology Attachment) cables are slower and older, which means that they are hardly used these days.

What are the types of SATA Cables?

The next thing you should know about SATA cables is their types. Their different types range from varying connector types and lengths to products made by differing brands. You need to note that the best SATA power cable will eventually depend on your requirements and setup. Hence, it is vital to know which cable is available before you purchase a cable.

Power and data are the two major principles of SATA cable types. The easiest way to spot the difference is that the power is larger and the data is smaller. Micro and Mini SATA cables are available too for internal hard drives and assemblies, including small-form components. The best choice is an eSATA cable, suited to outwardly linking laptops or desktop computers to external SATA devices like hard drives.

Types of SATA Cable Uses & Applications Definition
SATA-SATA Standard SATA applications Standard SATA cables available in different variety of lengths
SATA Power Connecting extensions, power adaptors, and splitters for data and SATA power cables SATA interface power cable
SATA Bridge Connecting ATA devices to PCI cards or SATA motherboards SATA interface performing as a bridge among devices
SATA Bracket Compatibility between eSATA drives and computer outputs Dual-port eSATA extension brackets
Micro SATA Backplane and Internal drives applications SATA data cable
Low Profile SATA Graphics cards Ultra-thin cables along with low profile connectors
e-SATA External connection to PCs Cable accessible in lengths ranging from 0.5 to 2 meters


How many SATA Cables do you Need?

Talking about the power requirement, you can attach a SATA cable with a drive by using a 15-pin connector. Maybe you need a single or more power cable and SATA connectors; depending upon whether you have a power cable (split) or not for the data cables, you need a SATA power supply for every hard drive. Take into consideration that the data cables do not have split ends, like SATA Power cables. Moreover, your cable requirement depends: on how many SATA ports you have, such as if you have six SATA ports, you cannot attach seven hard drives to a computer.

Final Verdict

Although fast technology PCI express is easily available, still latest laptops usually include purpose-made, built-in SATA cables, and they are much in use even these days. Nearly every latest hard drive uses the SATA interface, and a few legacy drives use the older PATA interface. As discussed above, these SATA power supplies are used widely to provide power to your laptop, PC, and to multiple internal storage devices. We hope that we have guided you in detail.
