PSG has now secured the season-opening cup on fourteen separate occasions.
Paris Saint-Germain needed a dramatic equaliser 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 Champions League holders appeared to be sailing towards a comfortable win in the match featuring the French league champions and the French Cup winners after the French winger opened the scoring in the opening stages.
However, Marseille struck two times late to seize a shock lead. First, the English forward converted from the spot-kick, before the defender inadvertently directed the ball into his own net for an own goal.
In a breathtaking turn of fortune, Goncalo Ramos snatched a crucial equaliser in the final seconds to force the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then stood as the hero, stopping crucial kicks from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all scored with composure for PSG to seal a 4-1 penalty win.
Now 14-time winners Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now lifted this trophy for the twelfth time in the last thirteen seasons.
