PSG has now won the prestigious cup on 14 separate occasions.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be sailing towards a straightforward triumph in the showdown featuring the French league winners and the French Cup holders after the French winger found the net in the opening stages.
However, the southern French side struck two times in the closing moments to take a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions PSG, 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 twelfth time in the past 13 years.
