Sunbeam is a teir 3 PSU but only by name not model, now if the specs are accurate and you hook each of the 2 6pin connectors to the VC from seperate rails since it is only 28amps per rail and your VC states 36amps required you should be ok. I would recomend you look at a teir 2 PSU although they are more expensive the quality and peace of mind would far outweigh the cost.
