The Parisian club has now claimed the season-opening cup on fourteen separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the showdown between the French league champions and the French Cup winners 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 shock lead. First, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital leveler in the dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past thirteen years.
