The card uses 2 connectors and if the PSU provides two cables to connect it fine if not it will work fine if both connectors come on the same cable since it is a single +12 volt rail PSU.
The PSU only supplied the 8-pin PCI-E to (2) 6+2 PCI-E splitter cable. I was fully prepared to use this setup, but AMD "recommends" using to individual cables rather than the splitter cable. This would require having a 6-pin PCI-E X 6+2 PCI-E (female-female) and I just can't seem to find such an animal.
If the splitter setup would work, that would be awesome. AMD says (2) separate 75W PCI-E connections. I'm just not smart enough to figure what I'd be pulling per connection through that splitter setup.
