PSG has now claimed the season-opening trophy on 14 separate occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown featuring the French league champions and the Coupe de France holders after the French winger found the net in the opening stages.
However, Marseille fired two times in the closing moments to take a surprise lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain 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 lifted this competition for the twelfth time in the past thirteen seasons.
