PSG has now secured the prestigious cup on 14 separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the French Cup holders after the French winger found the scoring early on.
However, the southern French side struck twice late to seize a surprise advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a convincing penalty win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past thirteen years.
