PSG has now claimed the season-opening cup on 14 different times.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
However, the southern French side fired two times late to seize a surprise lead. Initially, the English forward converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, saving crucial attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and the young talent all converted successfully for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this trophy for the 12th time in the last thirteen years.
