PSG has now secured the season-opening cup on 14 different occasions.
The Parisian giants required a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive French Super Cup victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side struck two times in the closing moments to take a shock lead. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial leveler in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who met 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 past 13 years.
