The Parisian club has now secured the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the French Cup winners after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker grabbed a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to complete a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last 13 seasons.
