PSG has now won the prestigious trophy on fourteen different times.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight French Super Cup victory.
The European champions appeared to be coasting towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille fired twice in the closing moments to take a shock advantage. First, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial leveler in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from O'Riley and Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a 4-1 shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen years.
