The Parisian club has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable triumph in the match featuring the French league winners and the French Cup holders after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times in the closing moments to take a shock advantage. First, the English forward scored from the spot-kick, before the defender inadvertently directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker snatched a vital equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to seal a convincing shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past thirteen years.
