The Parisian club has now won the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown between the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring early on.
However, Marseille struck twice late to take a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a crucial leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the past thirteen seasons.
