The Parisian club has now secured the prestigious trophy on 14 different occasions.
The Parisian giants required a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be sailing towards a comfortable triumph in the match between the French league champions and the Coupe de France holders after the French winger found the scoring in the opening stages.
Yet, the southern French side struck two times in the closing moments to seize a shock lead. First, Mason Greenwood scored from the spot-kick, before the defender inadvertently 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 dying moments to send the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and Desire Doue all scored successfully for PSG to seal a convincing penalty win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the 12th time in the past 13 seasons.
