PSG has now claimed the season-opening cup on fourteen different times.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, Marseille fired twice in the closing moments to take a surprise advantage. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for PSG to complete a convincing penalty victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the last 13 seasons.
