PSG has now won the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck two times in the closing moments to take a surprise advantage. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this competition for the twelfth time in the last 13 seasons.
