The Parisian club has now claimed the season-opening trophy on 14 separate times.
The Parisian giants needed a stoppage-time equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and capture a fourth straight French Super Cup title.
The European champions appeared to be coasting towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, Marseille fired twice late to take a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial equaliser in the final moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty victory.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last thirteen years.
