PSG has now secured the prestigious cup on fourteen different occasions.
Paris Saint-Germain needed a stoppage-time equaliser followed by a perfect spot-kick decider 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 comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the net early on.
Yet, the southern French side fired twice late to take a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho inadvertently directed the ball into his own net for an own-goal.
In a remarkable turn of events, Goncalo Ramos snatched a vital equaliser in the final seconds to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored with composure for Paris Saint-Germain to seal a convincing penalty win.
The record champions PSG, who faced last season's Ligue 1 second-placed team Olympique de Marseille after achieving a domestic double, have now won this competition for the twelfth time in the past thirteen seasons.
