PSG has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders seemed to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup holders after Ousmane Dembele opened the net in the opening stages.
However, the southern French side fired two times late to take a shock lead. First, Mason Greenwood converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a vital leveler in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past thirteen seasons.
