The Parisian club has now won the season-opening cup on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and capture a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele found the net early on.
However, the southern French side fired two times in the closing moments to seize a surprise lead. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a crucial equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last 13 years.
