The Parisian club has now secured the prestigious cup on fourteen separate 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 victory.
The Champions League holders seemed to be coasting towards a comfortable win in the match between the French league winners and the Coupe de France winners after the French winger opened the net in the opening stages.
However, the southern French side fired two times late to take a surprise lead. First, the English forward converted from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to complete a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen seasons.
