The Parisian club has now claimed the season-opening cup on fourteen different times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring early on.
Yet, the southern French side fired two times late to take a surprise advantage. First, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial leveler in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a convincing penalty win.
The record winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
