PSG has now claimed the season-opening trophy on fourteen different occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward win in the showdown featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, Marseille struck twice in the closing moments to take a shock advantage. Initially, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker snatched a vital equaliser in the dying moments to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now won this competition for the twelfth time in the past 13 seasons.
