PSG has now claimed the season-opening cup on 14 different occasions.
The Parisian giants required a dramatic equaliser followed by a perfect spot-kick decider to overcome Marseille in Kuwait and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable win in the showdown between the French league champions and the French Cup holders after the French winger found the net in the opening stages.
However, Marseille fired two times late to seize a surprise lead. Initially, 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 remarkable turn of events, the Portuguese striker snatched a crucial equaliser in the dying seconds to send the contest into a penalty shootout. PSG goalkeeper Lucas Chevalier then emerged as the key figure, stopping crucial attempts from O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and the young talent all converted with composure for PSG to complete a convincing shootout victory.
The record champions Paris Saint-Germain, who met last season's Ligue 1 second-placed team Marseille after completing a domestic double, have now won this competition for the twelfth time in the last 13 seasons.
