The Parisian club has now claimed the season-opening trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 winners and the French Cup winners after the French winger found the net early on.
Yet, Marseille fired twice late to seize a shock lead. First, the English forward converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker snatched a vital leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the 12th time in the past 13 years.
