The Parisian club has now claimed the prestigious cup on fourteen separate times.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be coasting towards a comfortable win in the showdown between the French league winners and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side struck twice in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt 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 shootout win.
Now 14-time winners 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 12th time in the last 13 seasons.
