The Parisian club has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired two times late to take a surprise lead. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a convincing shootout win.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last thirteen years.
