The Parisian club has now secured the season-opening trophy on 14 separate times.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward win in the showdown between the Ligue 1 winners and the Coupe de France holders after Ousmane Dembele opened the scoring early on.
Yet, Marseille fired twice in the closing moments to take a shock advantage. First, the English forward scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a vital equaliser in the final seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the twelfth time in the past thirteen years.
