PSG has now claimed the prestigious cup on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
However, the southern French side fired twice in the closing moments to seize a surprise advantage. Initially, Mason Greenwood converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker snatched a crucial leveler in the dying seconds to force the contest into a deciding shootout. PSG goalkeeper Chevalier then emerged as the key figure, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted with composure for PSG to seal a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past 13 years.
