Noren bulldozed his way through the pack on the final day at Wentworth, producing eight birdies before an eagle at the last to cap a brilliant display and a two-shot win with a closing 10-under 62 to land the title in what was a record for the revamped course.
Beginning two hours before the leaders and with 22 players teeing off after him, Sweden's 34-year-old Monaco resident charged past the lot with a stunning 62 featuring no fewer than eight birdies and an eagle.
The two-time European Tour victor, with fellow Tour player Dimi Papadatos on the bag, shot an impressive 68 in his third round despite windy conditions, but predicted he would be full of nerves come Sunday.
While Noren exploded, numerous top contenders faltered.
"Wentworth is such a tough course mentally", Noren said.More news: Theresa May to form government with DUP backing
The 31-year-old reserved his best round of the week for the toughest conditions, with just one bogey in swirling winds at Wentworth, and he will start Sunday's round one clear of Branden Grace. He played just twice in 2014 because of wrist problems but I think he's kind of found his formula and it's obviously working.
"The last seven holes were a little bit easier playing downwind compared to the first two days", he said afterwards. "Yeah, a lot of positives I suppose".
His playing partner Peter Uihlein eulogised about the round saying it was the best he had ever seen.
The Swede entered the final round at Wentworth's West Course at one-under, but had an unbelievable performance that featured eight birdies, zero bogeys, and this eagle on 18 that gave him the lead.
"So my confidence goes up and just to work towards my goals and improve on my weaknesses and my strengths and try to figure out where I'm losing shots and gaining shots".
Lee Westwood began the day in contention but fell away after shooting one over to make him four under for the four rounds.
"You had to hit just quality shots". He had another double bogey on 17 but he finished with a superb eagle on 18 for a share of sixth place.
"It feels incredible and insane because I had no intention of trying to win this morning", said Noren. "If I can go out and shoot 68 tomorrow, you never know what might happen to the leaders and we might be in with a shout still".
