PSG has now secured the season-opening trophy on fourteen different times.
The Parisian giants needed a dramatic leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be sailing towards a comfortable win in the match between the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
Yet, Marseille fired two times in the closing moments to seize a surprise lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final moments to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
