PSG has now won the season-opening trophy on fourteen different times.
The Parisian giants required a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the net early on.
However, the southern French side fired two times late to seize a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker snatched a vital leveler in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past thirteen seasons.
