The Parisian club has now secured the season-opening trophy on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight French Super Cup title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the net early on.
Yet, the southern French side struck two times in the closing moments to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to seal a convincing penalty victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the 12th time in the past thirteen years.
