PSG has now won the season-opening trophy on 14 separate occasions.
The Parisian giants needed a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the match between the French league champions and the French Cup winners after Ousmane Dembele found the scoring early on.
Yet, Marseille struck two times 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 breathtaking turn of events, Goncalo Ramos snatched a vital leveler in the dying moments to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, saving crucial kicks from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, the midfielder, the full-back, and the young talent all scored with composure for Paris Saint-Germain to complete a convincing shootout victory.
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 last 13 years.
