The Parisian club has now won the prestigious trophy on 14 different times.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league winners and the Coupe de France winners after the French winger found the net in the opening stages.
However, the southern French side struck two times in the closing moments to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker snatched a crucial leveler in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a convincing penalty win.
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 lifted this trophy for the 12th time in the last thirteen seasons.
