The Parisian club has now claimed the season-opening cup on fourteen different times.
The Parisian giants required a stoppage-time leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the Coupe de France holders after the French winger opened the net in the opening stages.
Yet, Marseille struck two times in the closing moments to take a surprise lead. 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 fortune, the Portuguese striker grabbed a vital leveler in the final moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a 4-1 shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past thirteen seasons.
