Do I need an external power supply for my graphics card?

Hi there!

I recently bought the Gigabyte Radeon Graphics Card GDDR5 (http://www.amazon.co.uk/Gigabyte-Radeon-Graphics-GDDR5-PCI-E/dp/B007PJVB3Y) to upgrade my graphics on my bog standard Dell computer. After some faffing about, I managed to get the massive card to fit into the slot inside the computer case. However, I didn't realise that the card needed a power supply and I can't see any spare connectors coming out of the power supply in my computer.

Is it possible to just buy an external power supply to power only the graphics card? Or would I need to rewire everything?

Any help would be much appreciated.

Cheers!
