The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to get past Marseille in the Gulf and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after the French winger opened the net in the opening stages.
However, Marseille struck two times late to take a surprise lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos snatched a crucial equaliser in the final moments to send the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this trophy for the twelfth time in the past 13 years.
