PSG has now won the season-opening trophy on fourteen different occasions.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, the southern French side struck two times late to seize a surprise lead. First, Mason Greenwood scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 shootout win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the last 13 years.
