PSG has now secured the season-opening cup on fourteen different times.
Paris Saint-Germain required a stoppage-time equaliser followed by a perfect spot-kick decider to overcome Marseille in the Gulf and capture a fourth straight Trophee des Champions title.
The Champions League holders appeared to be coasting towards a straightforward win in the match featuring the Ligue 1 winners and the Coupe de France holders after the French winger found the scoring in the opening stages.
Yet, Marseille struck twice late to take a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho unfortunately turned the ball into his own net for an own-goal.
In a remarkable turn of events, the Portuguese striker grabbed a vital equaliser in the dying moments to force the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then emerged as the key figure, stopping decisive attempts from O'Riley and Traore.
From the spot, Ramos, the midfielder, the full-back, and the young talent all scored successfully for PSG to complete a 4-1 shootout win.
The record champions PSG, who faced last season's Ligue 1 runners-up Olympique de Marseille after completing a domestic double, have now won this trophy for the twelfth time in the last thirteen seasons.
