PSG has now secured the prestigious cup on fourteen separate times.
Paris Saint-Germain needed a dramatic equaliser followed by a successful spot-kick decider to overcome Marseille in Kuwait and capture a fourth straight Trophee des Champions victory.
The Champions League holders seemed to be sailing towards a straightforward triumph in the match between the Ligue 1 winners and the Coupe de France winners after Ousmane Dembele found the scoring in the opening stages.
Yet, the southern French side struck two times late to take a shock lead. Initially, the English forward scored from the spot-kick, before the defender unfortunately directed the ball into his own net for an own goal.
In a remarkable twist of events, Goncalo Ramos grabbed a vital equaliser in the dying seconds to send the contest into a deciding shootout. PSG goalkeeper Lucas Chevalier then emerged as the hero, stopping decisive attempts from O'Riley and Hamed Traore.
In the shootout, Goncalo Ramos, Vitinha, the full-back, and Desire Doue all converted successfully for Paris Saint-Germain to complete a 4-1 penalty win.
The record champions PSG, who faced last season's Ligue 1 runners-up Marseille after completing a domestic double, have now won this trophy for the 12th time in the last thirteen seasons.
