PSG has now secured the season-opening trophy on 14 separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable triumph in the match between the French league champions and the French Cup holders after Ousmane Dembele opened the net early on.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial leveler in the final moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a convincing shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the past thirteen years.
