The Parisian club has now won the season-opening cup on fourteen separate times.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck two times late to take a shock advantage. Initially, the English forward scored from the penalty spot, 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 vital equaliser in the dying moments to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a 4-1 shootout win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last thirteen years.
