PSG has now claimed the prestigious cup on 14 separate occasions.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to overcome Marseille in the Gulf and secure a record-extending fourth consecutive French Super Cup victory.
The European champions seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele found the scoring early on.
However, the southern French side struck two times in the closing moments to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing penalty win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this trophy for the 12th time in the last thirteen years.
