PSG has now claimed the season-opening cup on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a comfortable win in the match between the Ligue 1 winners and the Coupe de France winners after the French winger opened the scoring early on.
However, the southern French side struck twice late to seize a shock advantage. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the dying seconds to force the contest into a penalty shootout. The Parisian shot-stopper Chevalier then emerged as the hero, stopping decisive kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, Nuno Mendes, and the young talent all scored with composure for Paris Saint-Germain to complete a 4-1 penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen years.
