This particular card requires a [combined] rating of 24A on the +12v rail, and a single 6-pin connector.
The generic psu (no brand labeled, came with el cheapo power-up case) I'm running on for the moment is 450w and 25A on a single +12v rail. I wouldn't trust it with my new investment, and barely trust it with my newer build. I can't get a new psu just yet. A friend sent me one via mail, but they didn't know all the specifications and didn't have whatever paperwork would have come with it. I couldn't locate a non-broken link to the company's website.
To get to the point, it is an Ultra xFinity 800w. Model# ult-xf800g. It has four +12v rails, each rated at 20A, combined wattage 660. There are two 6-pin connectors, one labeled "+12v 3" and the other "+12v 4". Are these all single, then? Or combined?
I need to know if its worth the risk connecting my new card to them. If not, I'll just wait and get the corsair I have my eye on. I would, however, like to have a graphics card again.
