PSG has now secured the prestigious cup on 14 separate occasions.
Paris Saint-Germain required a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and secure a fourth straight Trophee des Champions victory.
The European champions seemed to be sailing towards a comfortable triumph in the match featuring the Ligue 1 winners and the Coupe de France winners after the French winger opened the net in the opening stages.
However, the southern French side fired twice late to take a shock lead. Initially, 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 remarkable twist of events, Goncalo Ramos snatched a vital equaliser in the dying seconds to send the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Ramos, Vitinha, the full-back, and Desire Doue all converted with composure for PSG to complete a convincing penalty victory.
The record winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Olympique de Marseille after achieving a league and cup double, have now lifted this trophy for the 12th time in the last 13 years.
