PSG has now secured the prestigious cup on fourteen separate times.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable win in the match between the Ligue 1 champions and the French Cup holders after the French winger opened the scoring early on.
Yet, Marseille struck twice late to seize a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the dying seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to seal a 4-1 shootout 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 thirteen seasons.
