PSG has now secured the season-opening cup on fourteen separate times.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the Ligue 1 champions and the Coupe de France holders after Ousmane Dembele opened the scoring in the opening stages.
However, the southern French side struck two times late to seize a shock advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a breathtaking turn of fortune, the Portuguese striker grabbed a vital leveler in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to complete a convincing shootout win.
Now 14-time champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after achieving a domestic double, have now won this trophy for the 12th time in the past 13 seasons.
