PSG has now claimed the prestigious cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a perfect penalty shootout 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 triumph in the showdown featuring the French league champions and the French Cup winners after the French winger found the scoring early on.
However, Marseille struck two times late to seize a shock advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted 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 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the last 13 years.
