[ Firstly this question doesn’t violate Rule No. 3 of the Community, as I need technical help not economical ]

I want to buy a 3.5" SATA HDD to USB connector. To transfer data from my old HDD to SSD.

I found this https://www.amazon.in/WeFly-USB-3-0-SATA-Adapter/dp/B0CWS2DZKV/

As far as I know, 3.5" SATA HHD needs extra power supply. This adapter I found Amazon has separate 12V/2A port ( power adapter not included). Also it has 2 USB ports.

Now, my question is will the second USB draw the power needed from the Laptop itself? Or do I must have separate power supply?

If the answer is the latter, why is there a second USB?

I do already have a 12V/1A power supply. But my HDD requires 5V/0.75A + 12V/0.75V.

My HDD👇🏽

Idk If this Community the is appropriate one for this question, but idk where else to ask on lemmy.

    I’m curious, can you elaborate why you need this connector?

    To answer your questions, those two USB A connectors are for power and data transfer, separately. But if you got a 3.5" drive, you’re going to need that external 12V power supply anyway.

    You can plug the data USB connector into the same PC to manage the files, but you can also put it in a different PC, so to transfer files between two devices quickly.

    You can also use a power bank for the USB A power connector, but this will again only work with the 2.5" drives.

      To transfer data from my old HDD to SSD.

      So as per the other person’s reply

      Original usb ports often maxed out at 500ma.

      So If I used 2 USBs (one for data and other for 500ma) + 12V/1A power supply, will it suffice my need of 5V/0.75A + 12V/0.75V?
