The Parisian club has now claimed the prestigious trophy on fourteen different times.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the Coupe de France holders after Ousmane Dembele found the scoring early on.
Yet, Marseille fired two times in the closing moments to take a surprise lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a 4-1 shootout victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen years.
