The Parisian club has now claimed the prestigious trophy on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown featuring the French league champions and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck two times late to seize 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 turn of events, the Portuguese striker grabbed a crucial leveler in the dying moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past 13 years.
