PSG has now won the season-opening cup on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match between the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, Marseille struck two times in the closing moments to take a shock advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital equaliser in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a convincing penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
