The Parisian club has now won the prestigious cup on 14 separate times.
The Parisian giants required a stoppage-time leveler followed by a successful spot-kick decider to get past Marseille in Kuwait 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 between the French league winners and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side fired two times late to take a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial leveler in the final seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 years.
