PSG has now secured the season-opening trophy on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, Marseille struck twice late to take a shock advantage. First, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a convincing penalty victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 seasons.
