The Parisian club has now won the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the net early on.
Yet, the southern French side struck two times late to seize a surprise advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving decisive kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the last thirteen years.
