The Parisian club has now claimed the prestigious cup on 14 different occasions.
The Parisian giants needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. First, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos snatched a vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a convincing penalty win.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the 12th time in the last thirteen seasons.
