The Knights then scored three unanswered tries while Sims was in the sinbin for a high shot on Hastings to take an 18-12 halftime lead.
Greg Marzhew was the first to cross in the 36th minute after five-eighth Tyson Gamble stepped across the face of the defence before linking with Best to put the winger over out wide.
Lachlan Fitzgibbon then scored one of the best tries of the season after the Knights shifted the ball through 10 sets of hands, with Tyson Frizell and Jackson Hastings handle twice, in the 39th minute.
Ponga missed both conversions but Newcastle showed their intent to carry on with the job when Matt Croker scored in the 45th minute as Sims was waiting to return to the field.
The Knights only other points came from a 75th minute Ponga penalty goal but their defence limited the Storm to just one second half try through Papua New Guinea centre Justin Olam and they hung on to win.
