The Parisian club has now secured the season-opening trophy on 14 different times.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger opened the net in the opening stages.
However, the southern French side fired twice late to take a shock advantage. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
