The Parisian club has now won the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The Champions League holders appeared to be sailing towards a comfortable win in the showdown between the French league winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side fired two times late to take a shock advantage. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital equaliser in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from Matt O'Riley and Traore.
In the shootout, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 penalty victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
