PSG has now claimed the season-opening trophy on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match between the French league champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck two times in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to seal a convincing penalty win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the past thirteen seasons.
