PSG has now secured the season-opening cup on 14 separate times.
The Parisian giants required a dramatic leveler followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and secure a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders appeared to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the French Cup winners after the French winger found the scoring early on.
Yet, the southern French side fired twice late to take a shock lead. 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 remarkable turn of fortune, the Portuguese striker grabbed a vital equaliser in the dying moments to send the match into a penalty shootout. PSG goalkeeper Chevalier then stood as the hero, saving decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and Desire Doue all converted with composure for PSG to complete a 4-1 penalty victory.
Now 14-time winners PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the last 13 seasons.
