PSG has now claimed the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the French league winners and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
However, Marseille struck twice late to seize a surprise advantage. Initially, Mason Greenwood scored 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 grabbed a crucial leveler in the final moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
