PSG has now claimed the prestigious trophy on fourteen separate times.
Paris Saint-Germain needed a stoppage-time leveler followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The Champions League holders appeared to be sailing towards a straightforward win in the match between the Ligue 1 winners and the Coupe de France winners after the French winger opened the scoring early on.
However, the southern French side struck twice in the closing moments to seize a shock lead. First, the English forward scored from the penalty spot, before the defender inadvertently directed the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a vital equaliser in the final seconds to force the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then stood as the key figure, stopping crucial attempts from O'Riley and Traore.
From the spot, Goncalo Ramos, the midfielder, Nuno Mendes, and the young talent all scored with composure for PSG to seal a 4-1 shootout win.
The record champions Paris Saint-Germain, who faced last season's Ligue 1 runners-up Marseille after completing a league and cup double, have now won this competition for the 12th time in the past 13 seasons.
