[ 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.

    Original usb ports often maxed out at 500ma. You probably won’t need the second usb on a modern system, but you will need the 12v adapter. (usb maxes out at 5v)

    Also, this is the wrong community.

      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?

      you will need the 12v adapter

      Not if there’s something like a boost converter built in.

      I don’t know what you can draw from a modern USB port, but 12.75W is required by the drive, and when I tried a couple of months ago, I wasn’t able to power a similar drive (it had a green and white label and was 1 TB, IDK what it was anymore) from a single USB-C port.
