PSG has now claimed the prestigious cup on 14 separate occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a comfortable triumph in the showdown featuring the French league champions and the Coupe de France winners after Ousmane Dembele found the net early on.
Yet, the southern French side fired two times in the closing moments to take a surprise advantage. Initially, Mason Greenwood scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable twist of fortune, Goncalo Ramos grabbed a vital equaliser in the dying seconds to force the match into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive attempts from Matt O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for Paris Saint-Germain to seal a 4-1 penalty victory.
The record champions PSG, who faced last season's Ligue 1 second-placed team Marseille after achieving a league and cup double, have now lifted this competition for the 12th time in the past thirteen years.
