The Parisian club has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a comfortable win in the showdown featuring the French league winners and the French Cup holders after the French winger found the scoring early on.
However, Marseille struck twice late to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to seal a 4-1 shootout victory.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the 12th time in the past 13 seasons.
