The Parisian club has now claimed the season-opening cup on 14 different times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be sailing towards a straightforward win in the showdown between the French league winners and the Coupe de France winners after Ousmane Dembele found the net early on.
Yet, the southern French side fired two times in the closing moments to take a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital leveler in the dying moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the past 13 years.
