The Parisian club has now claimed the season-opening trophy on fourteen different times.
The Parisian giants needed a stoppage-time leveler followed by a successful spot-kick decider to get past their arch-rivals in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions appeared to be coasting towards a straightforward triumph in the showdown featuring the French league champions and the Coupe de France holders after the French winger found the scoring early on.
However, the southern French side fired twice late to take a shock lead. First, Mason Greenwood converted from the penalty spot, before the defender unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of events, the Portuguese striker grabbed a crucial equaliser in the final moments to force the match into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, saving crucial kicks from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to complete a 4-1 penalty win.
The record champions PSG, who met last season's Ligue 1 runners-up Marseille after achieving a league and cup double, have now won this trophy for the twelfth time in the past 13 years.
