PSG has now secured the prestigious cup on fourteen separate occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the match featuring the Ligue 1 winners and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
Yet, the southern French side fired two times in the closing moments to take a shock 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 remarkable twist of events, Goncalo Ramos grabbed a vital leveler in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored successfully for Paris Saint-Germain to seal a 4-1 shootout victory.
Now 14-time winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last 13 years.
