not sure where to start, shouldn't be hard but since I am worse than a newbie I don't even know where to start.
MXM socket (PCIE, but for laptop GPU) has many pins, but only need PCB that connects to pins "12v, 5v, 3.3v & GRND" and output to a sata 15 pin power cable to power 12v hardware (laptop default sata is only 5v, but no 12v rail). I have included schematic diagram for MXM with which pins has 12v/5v/3.3v etc, pls help!.
schematic diagram for MXM
MXM slot
A PCB design I have in mind (one in picture outputs something else no idea what it is, but need similar one that outputs sata 15 pin power including 12v rail)
finally sata 15 pin
