PSG has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 champions and the French Cup winners after the French winger found the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to seize a surprise advantage. First, the English forward converted from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, the Portuguese striker snatched a crucial leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
The record 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 competition for the twelfth time in the past 13 years.
