as has been said, the PSU is not good, cheap dodgy manufacturers from china often over-rate their PSU's. The only way it would produce 850w would be in a very short burst upon explosion. Stick with reputable brands that live up to their power ratings like Antec, Corsair, Seasonic, XFX. If not buying from a reputable manufacturer always try to find a review where they load test the psu. For that setup a 550-600w unit would be preferable.

2 good articles abou PSU's you should definitely read:

in this review its a 750w psu that can barely produce 450w, this would be a similar story for your psu:
