The Parisian club has now secured the season-opening cup on 14 different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 winners and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, Marseille fired twice late to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to complete a convincing penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last thirteen years.
