The Parisian club has now won the season-opening trophy on 14 different occasions.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the Coupe de France winners after the French winger found the net early on.
Yet, Marseille fired twice in the closing moments to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to seal a 4-1 penalty victory.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past 13 seasons.
