The Parisian club has now claimed the prestigious cup on fourteen different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup winners after Ousmane Dembele found the net in the opening stages.
Yet, Marseille struck twice late to seize a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial leveler in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen years.
