PSG has now won the prestigious trophy on fourteen different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to get past Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions seemed to be sailing towards a comfortable triumph in the match between the French league champions and the Coupe de France holders after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired twice late to seize a surprise advantage. First, the English forward converted from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to send the match into a deciding shootout. The Parisian shot-stopper Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all scored with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last 13 years.
