PSG has now won the season-opening cup on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be coasting towards a straightforward triumph in the match featuring the Ligue 1 champions and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times late to take a surprise advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, the Portuguese striker snatched a vital leveler in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
