Hi guys! How to connect this cable(the black part) to the laptop power supply that I have("19.5VDC, 3.33ADC"):

0. Cable.

1. Power suply.

Funny all the genuine ads say its "18.5VDC" for the same part number(NSW 24187), but the label says (19.5VDC).

Update:
I think its something like this, but without the USB.

 

Red Black is 5V,, Yellow Black is 12V...

 

Thanks!
