The Parisian club has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown between the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, Marseille fired twice late to take a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last 13 years.
