PSG has now won the prestigious cup on 14 different occasions.
The Parisian giants needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be sailing towards a comfortable triumph in the showdown between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the net early on.
However, the southern French side fired twice late to seize a surprise lead. First, Mason Greenwood scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, Goncalo Ramos grabbed a crucial equaliser in the final moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now won this competition for the 12th time in the past thirteen seasons.
