The Parisian club has now claimed the prestigious cup on 14 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 capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be coasting towards a straightforward win in the match between the French league winners and the Coupe de France winners after the French winger found the scoring early on.
However, the southern French side struck twice in the closing moments to seize a shock advantage. 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 turn of events, the Portuguese striker grabbed a vital equaliser in the dying moments to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping crucial kicks from Matt O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and the young talent all converted successfully for PSG to seal a convincing penalty victory.
The record winners PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this competition for the twelfth time in the past thirteen years.
