Double check all your PSU connections: 24-pin motherboard, 4 or 8 pin CPU, HDD's. Make sure all connections are complete and solid.
That low end of a card likely wont have an external pci-e connection. But, there might be a connection to power the slot on the motherboard itself.

You can also try removing the GPU and using the on board connection. If the GPU is still in there, the system will usually default it.
