PSG has now secured the season-opening cup on 14 different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup winners after the French winger found the scoring in the opening stages.
Yet, the southern French side struck twice in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing 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 won this trophy for the twelfth time in the last 13 years.
