The Parisian club has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown between the French league winners and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille struck twice in the closing moments to seize a shock advantage. 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 fortune, Goncalo Ramos snatched a vital leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive attempts from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last 13 years.
