PSG has now won the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful spot-kick decider to overcome their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France holders after the French winger opened the net early on.
However, Marseille struck two times in the closing moments to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last 13 seasons.
