The Parisian club has now won the prestigious trophy on 14 separate times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the match between the Ligue 1 champions and the Coupe de France holders after the French winger opened the scoring early on.
Yet, Marseille struck two times late to take a shock advantage. Initially, Mason Greenwood converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final seconds to send the contest into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for Paris Saint-Germain to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the last 13 seasons.
