The Parisian club has now won the season-opening trophy on fourteen different times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck twice late to take a shock advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos snatched a crucial equaliser in the dying moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
