PSG has now secured the prestigious cup on fourteen separate times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a fourth straight French Super Cup title.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match between the French league winners and the Coupe de France holders after Ousmane Dembele found the scoring in the opening stages.
Yet, Marseille fired two times in the closing moments to seize a shock lead. First, Mason Greenwood converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable twist of fortune, Goncalo Ramos snatched a vital equaliser in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a convincing shootout win.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the past thirteen years.
