The Parisian club has now claimed the season-opening trophy on 14 separate occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to overcome their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a comfortable win in the match featuring the French league winners and the Coupe de France winners after Ousmane Dembele found the net in the opening stages.
Yet, the southern French side fired twice late to take a surprise advantage. First, the English forward converted from the penalty spot, before the defender unfortunately turned the ball into his own net for an own goal.
In a breathtaking twist of events, the Portuguese striker grabbed a vital equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, Nuno Mendes, and Desire Doue all converted with composure for Paris Saint-Germain to complete a convincing penalty win.
The record winners PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now lifted this competition for the twelfth time in the past thirteen years.
