PSG has now won the prestigious cup on fourteen different times.
The Parisian giants needed a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup holders after the French winger found the net in the opening stages.
However, the southern French side struck twice late to seize a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to seal a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last thirteen years.
