The Parisian club has now claimed the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to get past their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match between the French league winners and the Coupe de France winners after Ousmane Dembele opened the net early on.
Yet, Marseille fired twice in the closing moments to seize a surprise advantage. First, the English forward scored from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen seasons.
