The Parisian club has now secured the season-opening cup on 14 separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable win in the showdown between the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times in the closing moments to take a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial equaliser in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last thirteen seasons.
