The Parisian club has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille struck twice late to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout win.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last 13 years.
