The Parisian club has now secured the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful penalty shootout to get past 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 champions and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck twice late to seize a surprise lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a crucial leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this competition for the twelfth time in the past 13 seasons.
