The Parisian club has now claimed the prestigious trophy on 14 different times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille fired twice in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a convincing penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
