I have bought this cable in order to use a separate USB adapter to power my desktop hard disk (3,5")

USB to SATA

At one end is a normal USB male connector, and on the other end is an adapted 15-pin plug. These are the connected pins, I believe. Which I think they are correct pinned

SATA pinout

Should I connect anything else to turn the hard disk on? Or should this be enough? Am I doing anything wrong?

There are many cables like the one in the image below, but what I want is to manage the data cable be independent from the power cable. Is that possible? I was looking for a cable 7-pin SATA male to USB male but I couldn't find any. I want to connect the disk to a Raspberry and use a different power adapter to make it work.

data and power cable together

Any suggestion would be appreciated.

  • a) This is not a hardware request, & would be a better fit for superuser.com b) You didn't tell us what HDD you're trying to power.

  • Thanks for your comment @tetsujin. I'm trying to power this guy. Actually I'm looking for a hardware recommendation because actually my configuration is not working correctly. How can make this work?

    It says on the product link and the picture you posted that it will not work on 3.5" drives, because USB doesn't have a 12V rail. You need a dock with its own power supply.

  • Aaah you are right @tetsujin, I'm kind of blind haha. I thought it would work because I have a Qualcomm Quick Charger with 12V, that uses USB cable. So I don't know why they say that USB does not have 12V rail ¿? Thin, I would go for something like this with and adapter molex-SATA. Let's see if I don't blunder again

    It's your Qualcomm… & your right to test if the magic smoke leaks out when you try that ;)

That device won't work on 3.5" HDD drives because USB-A doesn't have the 12v rail those drives need.
USB-C has various ways of delivering higher power, but not USB-A.

The solution is an external power supply or something with USB-C with a PD specification.

  • Thanks for answering. As Tetsujin said in the comments I can't use that cable in my question with desktop hard disks. That was my mistake :/

  • Anyway I will need something similar to your suggestion to send just only the data through USB. I wonder why it is not very popular that kind of cable
