PSG has now claimed the prestigious cup on 14 different times.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side struck two times late to seize a surprise lead. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored successfully for PSG to complete a 4-1 penalty win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last 13 seasons.
