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.
I could not find anything in my references either.
Corsair and Seasonic are two brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty (in the USA). The warranty may be for a shorter period in other countries.
For a single GTX 460 rig, a good 550W PSU (such as the Corsair VX 550) will be plenty adequate considering even a highly overclocked CPU.. A 650W PSU is worth the consideration in case there any future plans going SLI with two of those GTX 460's..
