PSG has now won the prestigious cup on 14 different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown between the French league winners and the French Cup winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to seize a shock advantage. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to seal a convincing shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 years.
