The Parisian club has now claimed the season-opening cup on 14 different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a straightforward triumph in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side fired twice late to seize a surprise lead. First, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial leveler in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty win.
The record champions Paris Saint-Germain, who faced 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 13 years.
