The Parisian club has now won the prestigious cup on 14 separate times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the French league winners and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side fired two times in the closing moments to take a shock advantage. First, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
