PSG has now secured the season-opening cup on 14 different times.
The Parisian giants required a dramatic equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be coasting towards a straightforward win in the showdown between the Ligue 1 champions and the French Cup holders after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck twice late to take a surprise lead. First, the English forward converted from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker snatched a vital leveler in the final moments to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored successfully for PSG to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now lifted this trophy for the 12th time in the past thirteen seasons.
