The Parisian club has now secured the season-opening cup on fourteen different times.
The Parisian giants required a dramatic leveler followed by a perfect spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a comfortable triumph in the showdown featuring the Ligue 1 champions and the Coupe de France winners after Ousmane Dembele opened the net early on.
However, the southern French side struck twice late to take a surprise advantage. First, the English forward scored from the spot-kick, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking turn of events, Goncalo Ramos snatched a vital equaliser in the dying moments to send the match into a deciding shootout. PSG goalkeeper Chevalier then emerged as the hero, saving crucial attempts from Matt O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout win.
The record champions PSG, 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 12th time in the past thirteen years.
