The Parisian club has now won the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be coasting towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille fired twice late to take a surprise advantage. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital leveler in the final moments to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to seal a convincing penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 years.
