PSG has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup title.
The European champions appeared to be sailing towards a comfortable triumph in the showdown featuring the French league champions and the French Cup holders after Ousmane Dembele found the net early on.
Yet, the southern French side fired two times late to seize a surprise lead. First, Mason Greenwood 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 fortune, the Portuguese striker snatched a vital leveler in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 penalty victory.
The record winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen seasons.
