Hi guys!

Does anyone know how to connect this cable to a laptop, if its even possible?
Laptop: Dell E6320.
SATA part -> male
4 pin part -> female

 

What do you mean by connect? What is it you want to do?
It is a simple power cable, +5V, GND, GND, +12V.

 

How to power it from a laptop?

 

What type of drive are you trying to use. Laptops don't use drives that require 12V.

 

I need the 12V and 35W of power supply. Will it be possible with some USB C for 20A?

Something similar to this:

To be reworked for getting 35W from the SATA 15 pin. The SATA 15 pin will go to a molex 4 pin.

USB C -> SATA 15 pin -> Molex 4 pin. Or I can get some other way to power the Molex 4 pin, but I was hoping for a cheap and small solution.

I can build my own with LM2576, 2 channels for 12V and 5V.

 

I have 1 spare laptop power supply at 19V, 90W. I can use that too, unfortunately I don't know if the wires are separated inside. Otherwise I will still need the LM2576/LM2596, something like this:
