PSG has now won the prestigious trophy on 14 different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
However, Marseille fired two times late to seize a surprise lead. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen years.
