PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the showdown featuring the French league winners and the Coupe de France holders after the French winger found the scoring early on.
Yet, the southern French side struck two times late to take a shock advantage. Initially, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital leveler in the final moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for PSG to seal a convincing penalty victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last 13 years.
