PSG has now claimed the prestigious trophy on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be coasting towards a comfortable win in the showdown featuring the French league champions and the French Cup holders after the French winger found the net early on.
However, Marseille struck two times in the closing moments to take a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of events, Goncalo Ramos grabbed a crucial equaliser in the dying moments to force the match into a deciding shootout. The Parisian shot-stopper Chevalier then stood as the hero, saving decisive attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored successfully for PSG to complete a convincing shootout victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now won this competition for the twelfth time in the last thirteen seasons.
