PSG has now claimed the prestigious trophy on fourteen different times.
Paris Saint-Germain required a dramatic leveler followed by a perfect penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward triumph in the match between the French league champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
However, Marseille fired two times in the closing moments to take a shock advantage. Initially, the English forward converted from the penalty spot, 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 vital leveler in the final seconds to force the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the key figure, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record winners Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the last thirteen seasons.
