The Parisian club has now claimed the season-opening cup on 14 different occasions.
The Parisian giants needed a stoppage-time leveler followed by a perfect penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the match featuring the French league winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
However, Marseille fired two times in the closing moments to take a shock advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial leveler in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a convincing penalty win.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
