The Parisian club has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect penalty shootout 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 win in the showdown between the French league winners and the Coupe de France winners after Ousmane Dembele found the net early on.
However, Marseille fired twice late to seize a surprise advantage. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a crucial leveler in the dying 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 Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past 13 seasons.
