The Knights held a commanding 30-0 lead at half time before the Cowboys mounted a second half comeback to trail by just 30-18 with 20 minutes remaining.
But a runaway try from Newcastle five eighth Jarrod Mullen in the 61st minute prove to be the turning point.
Newcastle's victory celebrations may have been dampened with skipper Danny Buderus succumbing to a bicep injury just before full time.
The result sees the Knights move into eighth spot pending other round 24 fixtures, while the Cowboys continue to fight it out with the Bulldogs for the wooden spoon.
