The Parisian club has now claimed the season-opening cup on fourteen separate times.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 champions and the Coupe de France winners after the French winger found the scoring early on.
However, the southern French side fired twice late to seize a shock lead. Initially, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital equaliser in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 seasons.
