The Parisian club has now secured the prestigious cup on 14 separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown between the French league winners and the French Cup holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille struck twice in the closing moments to seize a shock lead. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout victory.
The record champions PSG, 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 12th time in the past thirteen seasons.
