The Parisian club has now won the season-opening cup on fourteen different times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the showdown between the French league winners and the French Cup holders after the French winger opened the scoring early on.
However, the southern French side struck two times late to take a shock lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial equaliser in the final moments to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
