The Parisian club has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward win in the match featuring the French league champions and the French Cup holders after the French winger found the scoring in the opening stages.
However, Marseille struck two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
Now 14-time champions 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 competition for the twelfth time in the past thirteen years.
