PSG has now secured the season-opening trophy on 14 different times.
The Parisian giants needed a stoppage-time leveler followed by a successful penalty shootout to overcome their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions title.
The European champions appeared to be coasting towards a straightforward win in the match featuring the French league champions and the Coupe de France winners after Ousmane Dembele opened the scoring early on.
Yet, the southern French side struck twice in the closing moments to take a surprise advantage. Initially, the English forward scored from the penalty spot, before the defender unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos grabbed a vital equaliser in the final moments to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive attempts from O'Riley and Hamed Traore.
In the shootout, Ramos, the midfielder, Nuno Mendes, and the young talent all converted successfully for PSG to complete a convincing shootout win.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now won this competition for the 12th time in the past thirteen seasons.
