PSG has now won the season-opening trophy on 14 different times.
Paris Saint-Germain needed a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a comfortable triumph in the match featuring the French league champions and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck twice late to take a shock advantage. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately directed 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 moments to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to seal a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the last 13 seasons.
