The Parisian club has now claimed the prestigious trophy on 14 separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the French league champions and the French Cup winners after Ousmane Dembele opened the net in the opening stages.
However, the southern French side fired twice late to take a shock lead. Initially, the English forward scored 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, Goncalo Ramos snatched a vital equaliser in the final moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the 12th time in the past thirteen years.
