The Parisian club has now claimed the prestigious trophy on fourteen separate occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the French league winners and the Coupe de France winners after the French winger opened the net early on.
Yet, Marseille fired two times in the closing moments to take a shock lead. First, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the 12th time in the past 13 years.
