The Parisian club has now won the season-opening cup on 14 separate occasions.
The Parisian giants needed a stoppage-time equaliser followed by a successful penalty shootout to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward triumph in the match between the French league champions and the French Cup holders after the French winger found the net in the opening stages.
Yet, Marseille struck twice late to take a surprise lead. First, Mason Greenwood scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to send the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing penalty win.
The record winners 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 competition for the twelfth time in the past 13 seasons.
