The Parisian club has now secured the season-opening trophy on fourteen separate occasions.
Paris Saint-Germain required a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in the Gulf and capture a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup winners after the French winger opened the net early on.
Yet, Marseille fired twice in the closing moments to seize a shock lead. Initially, 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 twist of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 penalty win.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
