The Parisian club has now claimed the season-opening cup on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille 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 Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, Marseille fired twice late to take a surprise advantage. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying moments to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the past thirteen seasons.
