PSG has now secured the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the Ligue 1 winners and the French Cup holders after Ousmane Dembele found the net early on.
Yet, the southern French side fired twice in the closing moments to seize a surprise lead. Initially, Mason Greenwood converted from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, Goncalo Ramos grabbed a crucial equaliser in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the last thirteen years.
