PSG has now claimed the prestigious trophy on 14 separate times.
Paris Saint-Germain needed a dramatic leveler followed by a successful penalty shootout to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the showdown between the Ligue 1 winners and the Coupe de France holders after the French winger found the net in the opening stages.
Yet, Marseille struck two times late to take a shock advantage. Initially, the English forward converted from the spot-kick, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking twist of fortune, the Portuguese striker grabbed a vital equaliser in the final moments to force the contest into a deciding shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, stopping crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and Desire Doue all scored successfully for PSG to complete a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 runners-up Marseille after achieving a domestic double, have now lifted this competition for the twelfth time in the past 13 years.
