Can You Add SATA Power Cables? (Here’s How To Do?)

Can You Add SATA Power Cables

Modern Power Supplies comes with at least 2 SATA power cables with three splitters. But the problem appears when you have an old PSU and don’t have enough SATA power cables left. In such a situation, one common question appears in people’s minds whether they can add extra SATA power cables or not.

Yes! It is possible to add SATA power cables, and there are primarily three ways to do this. You can add SATA power cables without using any adapters if you have a modular PSU. Secondly, if your PSU has a Molex connector left, then you can use male to female Molex to SATA connector. Thirdly, you can use SATA splitter cables, which is perhaps the best method.

If you are still confused about the methods of adding the SATA power cables, then all three methods are explained in depth below.

Method 1: Add SATA Cables Without Using Adapters

Usually, modern Power Supplies have more than 2 to 3 SATA connections, and if your PSU also has the same, then you can add SATA cables without using adapters.

But you can’t do this if you have a non-modular Power Supply because non-modular PSUs have fixed cables. It is only possible when you are using a semi-modular PSU or fully-modular Power Supply. The semi-modular ones have few detachable cables, while the fully-modular PSUs have all the detachable cables.

In the image, you can see the peripheral & SATA connector: These connectors usually come with enough cables to plug something into each spot. Some spots will be SATA, while some will be Molex.

Now, you can add an extra SATA power cable if you have open SATA power inputs left in the Power Supply. Still, you have to buy the cables that are specifically compatible with your Power Supply.

It is recommended to buy SATA electrical power modular cable from the PSU maker or a custom cable maker to ensure compatibility with your specific model power supply.

Many experts do not recommend adding SATA power cables in this way because buying an incompatible or wrong cable may end up with a 12v cable where there is a need for 3v. Moreover, it could have toasted components or catch fire in worst-case scenarios. Let’s check the second method.

Method 2: Using Molex to SATA Adapter

The 2nd method of adding a SATA power cable is by using the Molex to SATA power connector; these cables are usually very short in length and also very cost-effective. Check the Molex to SATA cable below-

You have to plug the four male Molex sides into the female Molex connector that comes with your Power supply, and on the other end, you can install drives according to your need.

If you don’t have the SATA power connector left, you can buy this type of Molex to SATA adapter, but there are some downsides to using this type of adapter.

These adapters have 5.5v red wire, 12v yellow wire, and ground connection black wires. These Molex to SATA adapters don’t have proper shielding; therefore, the electrical arc jumps from one voltage to another line, which can cause severe damage to the Power Supply, adapter, and other system components. However, fire may catch outside the PC case in a worst-case scenario.

Moreover, experts don’t recommend using these adapters because of losing all of their data.

Method 3: Using SATA Splitters Cables (Best Method)

As we noticed, both the methods explained above have some downsides, which is why this 3rd method will be considered best for you. Because, in this method, you just have to buy SATA splitter cables. Here’s an image of SATA splitter cables-

These cables are also cost-effective, and you can buy these cables here; I have picked the best SATA splitter cable for you. You can connect one end of the splitter cable to your power cable, and then you can install four drives by using these cables.

Final Thoughts

At the end of this article, I want to summarize everything for you; there are usually three ways to add SATA power cables, but using SATA splitter cables is perhaps the best method. Moreover, if you wish, then you can buy a new Power Supply with as much SATA power cable as you want.
