PSG has now secured the season-opening trophy on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time leveler followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown between the Ligue 1 winners and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
However, the southern French side fired two times in the closing moments to take a surprise advantage. First, the English forward scored from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of events, the Portuguese striker grabbed a crucial equaliser in the final seconds to force the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, saving crucial kicks from O'Riley and Traore.
From the spot, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last 13 seasons.
