PSG has now claimed the season-opening trophy on fourteen different occasions.
Paris Saint-Germain required a stoppage-time equaliser followed by a successful penalty shootout to get past Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions title.
The Champions League holders seemed to be coasting towards a straightforward win in the match between the French league champions and the French Cup holders after the French winger found the scoring in the opening stages.
Yet, the southern French side fired twice in the closing moments to take a surprise advantage. Initially, the English forward converted from the penalty spot, before Willian Pacho unfortunately directed the ball into his own net for an own-goal.
In a breathtaking turn of fortune, Goncalo Ramos grabbed a vital equaliser in the dying moments to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, saving crucial kicks from O'Riley and Traore.
From the spot, Ramos, Vitinha, the full-back, and the young talent all converted with composure for Paris Saint-Germain to complete a 4-1 penalty victory.
Now 14-time champions PSG, who faced 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 past thirteen years.
