The Parisian club has now claimed the season-opening cup on fourteen separate occasions.
The Parisian giants required a dramatic equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a straightforward win in the match featuring the French league champions and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck twice late to take a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the final moments to force the match into a deciding shootout. PSG goalkeeper Chevalier then stood as the key figure, saving crucial attempts from O'Riley and Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 penalty victory.
The record winners PSG, who met last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this competition for the 12th time in the last 13 years.
