The Parisian club has now won the season-opening trophy on fourteen different times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the showdown between the French league winners and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
However, Marseille struck two times in the closing moments to seize a surprise lead. Initially, Mason Greenwood scored from the penalty spot, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a crucial equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to seal a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the past thirteen years.
