I'd go with the EVGA in this case for two reasons. One is that it has a 10 year warranty vs the five year warranty of the XFX. The other is that Johnnyguru, who is pretty much the authority on PSU testing, gave the EVGA a 9.7 whereas he gave the XFX a 9.4. So they're basically both amazing PSU but one has a slight edge. You couldn't go wrong with either.
