PSG has now secured the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the showdown between the French league champions and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, the southern French side fired two times late to seize a shock advantage. First, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past 13 seasons.
