Which CM PSU?

Odds are it doesn't have enough plugs to run what you want. 650W bronze units don't have enough PCIe plugs to power it all. 650W gold units do, but even then it might be a stretch to do it. In general you want a 750W unit to handle two cards like this, more if you want to OC. I'm guessing you need a new PSU.
