The Parisian club has now claimed the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the French league winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to seize a surprise lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital leveler in the final moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time 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 last 13 years.
