PSG has now secured the season-opening cup on fourteen separate occasions.
The Parisian giants required a stoppage-time leveler followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the match featuring the French league champions and the French Cup winners after Ousmane Dembele found the net early on.
However, Marseille struck two times late to take a surprise lead. Initially, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker snatched a crucial leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to complete a 4-1 penalty win.
Now 14-time champions 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 trophy for the 12th time in the last thirteen seasons.
