The Parisian club has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the match featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
However, Marseille struck two times late to take a surprise advantage. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial leveler in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to seal a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen years.
