PSG has now claimed the season-opening cup on fourteen different times.
The Parisian giants needed a dramatic equaliser followed by a perfect spot-kick decider to get past Marseille in the Gulf and capture a record-extending fourth consecutive Trophee des Champions victory.
The European champions appeared to be coasting towards a comfortable triumph in the match featuring the Ligue 1 champions and the Coupe de France holders after the French winger opened the scoring early on.
However, the southern French side struck twice late to seize a shock lead. First, the English forward scored from the spot-kick, before Willian Pacho inadvertently turned the ball into his own net for an own goal.
In a remarkable turn of fortune, Goncalo Ramos grabbed a crucial leveler in the final seconds to send the match into a penalty shootout. The Parisian shot-stopper Lucas Chevalier then stood as the hero, stopping crucial attempts from Matt O'Riley and Hamed Traore.
From the spot, Goncalo Ramos, the midfielder, the full-back, and Desire Doue all converted successfully for PSG to complete a convincing shootout victory.
Now 14-time champions PSG, who met last season's Ligue 1 second-placed team Olympique de Marseille after completing a league and cup double, have now won this trophy for the 12th time in the past thirteen years.
