Best LP4 Molex to SATA Power Adapter 2020 Detailed Review.
Best LP4 Molex to SATA Power Adapter: When you’re installing a new SSD or HDD drive, there are two primary types of connection: Molex and SATA. Molex connections have four large pins, which are shaped similar to the ground prong on an AC cord.
SATA connections, on the other hand, have a flat, 15-pin design that looks much more advanced. Typically, Molex connections are found on older drives, or on larger 3.5 or 5.5-inch drives.
However, Molex connectors are too big to fit on a 2.5-inch drive. And as smaller drives have become the norm, SATA has gradually been replacing Molex as the format of choice.
The Cable Matters 4 Pin Molex to SATA Power Cable converts a female Molex plug to a female SATA plug. It’s 6 inches long, with a 4-pin male Molex plug on one end and a 15-pin SATA plug on the other.
The SATA connections are crimped, not molded, as you can clearly see in the photograph. This ensures that the operation is safe, and there won’t be any unexpected arcing.
These connectors also come in a three-pack. This is probably overkilled if you’re installing a single hard drive. But if you’re using an older power supply to build a new PC from scratch, you’ll have plenty of options.
One thing you’ll appreciate about the Cable Matters adapters is how easy they make cable management. At 6 inches in length, they’re ideal for reaching across most PC cases without extra bulk.
You won’t need to worry about finding somewhere to tie up the excess cable. That said, if you’ve got a very large PC case, some distances might be too far to bridge.
So, what might you do with the Cable Matters adapter? Well, it delivers standard 5.5-volt and 12-volt power, provided it’s connected to a standard 12-volt power supply.
This makes it compatible with the vast majority of PSUs and drives. Not only can you use it for installing a new SSD, but you can connect an HDD or even an optical drive.
Where the Cable Matters cables are designed to connect a single device, the Monoprice adapter is a complete wiring harness. Instead of a single SATA plug, it features four 15-pin SATA power connectors.
These connectors are spaced out every 6 inches across a set of 24-inch cables, making it easy to connect multiple drives. At one end, you’ll find a standard 4-pin molex connector.
The main reason to use the Monoprice adapter is if you’re building an entire PC around an old power supply. With a simple Molex connection, you can attach up to 4 SATA devices. That’s enough for an SSD, an HDD, and a Blu-Ray drive, with an extra plug left over for later expansion.
Like the Cable Matters adapter, the Monoprice adapter is designed to deliver 5-volt and 12-volt power. This is sufficient for the vast majority of hard drives, and it’s also good for most optical drives. However, keep in mind that some SATA devices require an additional 3-volt power supply.
The StarTech adapter is a little different than the last two options we looked at. Instead of converting a female Molex plug to a female SATA plug, it does the opposite. It converts a female SATA plug to a female Molex plug.
The cables are 12 inches in length, so you’ll have plenty of options for cable management. Like the Cable Matters and Monoprice adapters, the connections are all crimped. However, that’s less important on a SATA to Molex adapter than it is on a Molex to SATA adapter.
The StarTech power adapter is very well-designed. Not only are the connections crimped, but the 12-inch length accommodates almost any computer case. The overall quality is also excellent, including wide flanges on the ends that provide an easy grip.
So, why in the world would you want a SATA to Molex adapter? It sounds like going backward, and in a sense it is. But going backward isn’t always a bad thing.
Suppose, for example, that you’ve got some classic video games on floppy discs. If you’re trying to connect an older 3.5-inch floppy drive to a modern power supply, you’re liable to need one of these adapters.
So, which one of these power adapters is the best? It all depends on your hardware and your build. For connecting a single hard drive to an older power supply, the Cable Matters adapter is our top choice.
It’s 6 inches long, and it adapts your female Molex port to a female SATA port. It also comes in a 3-pack. While there are better options for connecting multiple devices, it’s good to have options.
Alternatively, the Monoprice adapter is a much better choice if you’re building a PC from scratch. The four integrated SATA plugs are attached to a single cable, which makes cable management a snap.
It also gives you the ability to connect multiple drives into a single plug. This is useful if you’re using an old PSU that doesn’t have a lot of plugs.
Finally, the StarTech adapter is the oddball on our list. Instead of connecting newer drives to an older PSU, it’s ideal for connecting an older drive to a newer PSU.
Considering the fact that technology is constantly advancing, it’s good to have a way to re-use your older drives. It’s safe to say that, no matter what you need, at least one of these adapters will be right up your alley.
