The Parisian club has now won the prestigious trophy on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the French Cup holders after the French winger found the scoring in the opening stages.
However, the southern French side fired twice in the closing moments to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital leveler in the final moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a 4-1 shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the last thirteen years.
