The Parisian club has now secured the prestigious trophy on fourteen separate occasions.
Paris Saint-Germain required a stoppage-time leveler followed by a successful spot-kick decider to get past their arch-rivals in the Gulf and secure a fourth straight French Super Cup title.
The European champions seemed to be sailing towards a comfortable win in the match between the French league winners and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side fired two times late to seize a shock advantage. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial leveler in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last thirteen seasons.
