Notes
USB Type-A to Molex 4-pin: USB provides power delivery through its own standard (USB PD). Connecting USB to a different power connector type is not safe without a purpose-built power supply with the correct output. The USB Type-A (USB) and Molex 4-pin (Power) are from different connector families.
