PSG has now claimed the prestigious trophy on 14 separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions 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, Marseille fired two times late to take a shock advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker grabbed a crucial leveler in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a 4-1 shootout victory.
Now 14-time champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last 13 years.
