PSG has now claimed the season-opening cup on fourteen different times.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net early on.
However, the southern French side fired two times late to seize a shock advantage. Initially, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
