The Parisian club has now secured the season-opening cup on 14 different times.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions title.
The Champions League holders appeared to be sailing towards a comfortable win in the match between the Ligue 1 champions and the Coupe de France winners after the French winger found the net in the opening stages.
Yet, the southern French side struck two times late to seize a surprise lead. First, Mason Greenwood converted from the penalty spot, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a breathtaking turn of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to force the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all converted with composure for Paris Saint-Germain to seal a convincing shootout victory.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the 12th time in the past thirteen years.
