The Parisian club has now secured the season-opening cup on 14 different occasions.
Paris Saint-Germain needed a dramatic equaliser followed by a successful penalty shootout to get past their arch-rivals in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The European champions seemed to be sailing towards a straightforward triumph in the showdown featuring the Ligue 1 winners and the Coupe de France winners after the French winger opened the net early on.
Yet, Marseille struck twice in the closing moments to take a surprise advantage. First, the English forward scored from the spot-kick, before the defender inadvertently turned the ball into his own net for an own-goal.
In a remarkable twist of events, the Portuguese striker snatched a vital equaliser in the dying moments to send the contest into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the hero, saving decisive kicks from O'Riley and Hamed Traore.
In the shootout, Ramos, Vitinha, the full-back, and the young talent all scored with composure for PSG to seal a convincing shootout victory.
The record champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a domestic double, have now lifted this competition for the 12th time in the past 13 years.
