The Parisian club has now won the season-opening cup on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable win in the match between the French league champions and the Coupe de France winners after Ousmane Dembele found the net early on.
However, Marseille struck two times in the closing moments to take a shock lead. Initially, the English forward scored from the penalty spot, 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 vital leveler in the final seconds to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
