PSG has now secured the prestigious cup on fourteen different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and capture a fourth straight French Super Cup title.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup winners after the French winger opened the scoring early on.
Yet, the southern French side fired two times in the closing moments to take a surprise lead. Initially, the English forward scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a vital leveler in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this competition for the 12th time in the last thirteen years.
