The Parisian club has now claimed the prestigious cup on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup holders after the French winger found the scoring in the opening stages.
However, Marseille fired two times late to seize a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing shootout win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past 13 seasons.
