PSG has now secured the season-opening trophy on 14 different occasions.
The Parisian giants required a stoppage-time leveler followed by a successful penalty shootout to get past Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup title.
The European champions seemed to be sailing towards a straightforward win in the showdown between the Ligue 1 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 seize a surprise lead. First, the English forward converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen years.
