The Parisian club has now won the prestigious trophy on fourteen separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful spot-kick decider to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown between the French league champions and the Coupe de France holders after the French winger opened the net early on.
Yet, the southern French side fired two times in the closing moments to seize a surprise advantage. First, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital leveler in the final moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial kicks from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last thirteen seasons.
