Hmm, not familiar with those psus. Also couldn't find any info on said psus. As always suggested here the best psus to get would be from corsair, enermax, seasonic, etc. That being said, 800w would be a bit much for your current list of parts. A good 650w from corsair or xfx would be good. If going for sli in the near future or for oc maybe go for 750w of corsair. I just don't see 800w as being efficient for your build.
