PSG has now claimed the prestigious trophy on 14 separate occasions.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in the Gulf and capture a fourth straight Trophee des Champions victory.
The European champions appeared to be sailing towards a straightforward win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele opened the net early on.
However, the southern French side fired two times in the closing moments to seize a shock advantage. First, the English forward converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital leveler in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 shootout victory.
Now 14-time winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the twelfth time in the past 13 seasons.
