The Parisian club has now claimed the prestigious cup on fourteen separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the French league winners and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, Marseille struck two times in the closing moments to take a shock lead. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial equaliser in the final seconds to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last thirteen years.
