PSG has now secured the prestigious trophy on 14 different occasions.
The Parisian giants needed a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a straightforward triumph in the match between the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele found the scoring early on.
However, Marseille fired two times in the closing moments to take a shock lead. Initially, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital equaliser in the dying seconds to send the match into a penalty shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving decisive kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all converted with composure for PSG to complete a convincing penalty victory.
Now 14-time champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the past thirteen years.
