PSG has now won the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward triumph in the showdown between the French league champions and the French Cup winners after Ousmane Dembele found the net early on.
Yet, Marseille fired two times late to seize a shock advantage. Initially, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past 13 years.
