The Parisian club has now won the season-opening trophy on fourteen different occasions.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the French Cup holders after the French winger opened the net early on.
However, the southern French side struck two times in the closing moments to seize a shock advantage. First, Mason Greenwood converted 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, Goncalo Ramos snatched a crucial equaliser in the final seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty victory.
Now 14-time winners 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 competition for the twelfth time in the last thirteen years.
