The Parisian club has now claimed the season-opening cup on fourteen different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward triumph in the match between the Ligue 1 champions and the French Cup winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side fired two times in the closing moments to seize a surprise advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial leveler in the dying seconds to force the match into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from Matt O'Riley and Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted successfully for PSG to complete a 4-1 shootout win.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
