The Parisian club has now won the season-opening trophy on 14 separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable win in the match featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the net early on.
However, Marseille fired two times in the closing moments to seize a shock lead. Initially, the English forward scored from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital equaliser in the final seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty victory.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the past thirteen seasons.
