The Parisian club has now won the prestigious cup on fourteen different occasions.
The Parisian giants required a stoppage-time equaliser followed by a perfect penalty shootout to get past their arch-rivals in Kuwait and capture a fourth straight Trophee des Champions victory.
The European champions seemed to be coasting towards a comfortable win in the showdown featuring the Ligue 1 winners and the French Cup holders after the French winger found the net early on.
Yet, the southern French side fired two times late to take a surprise advantage. Initially, the English forward scored from the penalty spot, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of fortune, the Portuguese striker grabbed a crucial equaliser in the final moments to send the match into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the key figure, stopping decisive attempts from Matt O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, Nuno Mendes, and Desire Doue all scored with composure for PSG to complete a convincing penalty victory.
The record champions PSG, who met last season's Ligue 1 runners-up Olympique de Marseille after completing a league and cup double, have now lifted this competition for the twelfth time in the last thirteen years.
