The Parisian club has now won the season-opening cup on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match between the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the scoring early on.
However, the southern French side fired two times in the closing moments to take a surprise lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a convincing penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
