PSG has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain required a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side struck two times late to take a shock lead. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the past 13 seasons.
