The Parisian club has now secured the season-opening cup on 14 different times.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired two times late to seize a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Chevalier then stood as the hero, saving crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for Paris Saint-Germain to complete a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now lifted this trophy for the twelfth time in the past thirteen seasons.
