PSG has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a dramatic leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille struck two times late to seize a shock advantage. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for PSG to complete a convincing shootout win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past 13 seasons.
