PSG has now claimed the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the net early on.
However, Marseille fired two times late to seize a shock lead. Initially, the English forward converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for PSG to seal a convincing penalty win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past 13 seasons.
