PSG has now claimed the prestigious cup on 14 separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a comfortable win in the showdown between the French league champions and the Coupe de France holders after the French winger opened the scoring in the opening stages.
Yet, the southern French side fired two times in the closing moments to seize a surprise advantage. First, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial leveler in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, the full-back, and Desire Doue all converted with composure for PSG to seal a convincing penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen years.
