PSG has now claimed the prestigious cup on fourteen separate times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and secure a record-extending fourth consecutive Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable win in the match featuring the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the scoring in the opening stages.
Yet, Marseille fired twice in the closing moments to seize a surprise advantage. First, the English forward converted from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the dying seconds to force the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a convincing shootout victory.
Now 14-time 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 13 seasons.
