The Parisian club has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and secure a fourth straight French Super Cup victory.
The Champions League holders appeared to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to take a shock lead. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a breathtaking twist of events, Goncalo Ramos snatched a crucial equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for PSG to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the 12th time in the last 13 years.
