A very nice PSU to be perfectly honest, 80+ gold rated from a very well known brand. There are alternatives which would yeald results almost as good at a much cheaper price but if you have the money then id get it :-)

It's an outstanding PSU. It's a 750W PSU - not 850W. What are your system specs?
How did you test the PSU to make sure it was defective? What were your indications that the PSU was faulty?
