The Parisian club has now secured the season-opening cup on 14 separate occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, Marseille fired two times in the closing moments to seize a surprise advantage. First, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the dying moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last thirteen years.
