Noren, who finished at 9-under 275 at Celtic Manor Resort, was two strokes better than Anders Hansen (even-par 71) and Gregory Bourdy (4-under 67).
Peter Hanson and Anders Hansen came into the final round trailing Noren by a single stroke, but Hansen quickly stumbled with a double-bogey on No. 2 and while Hanson found the water hazard on No. 6, also carding a double-bogey followed with another bogey.
Hanson (72) finished tied for third at minus-six with Ricardo Gonzalez (67), Pablo Larrazabal (67) and Johan Edfors (69).
Noren's win was the second of his European Tour career and first since the 2009 European Masters.
