You have two options as I see it.

1. You can chance it and try to use the installed power supply with the graphics cards by using possibly included Molex to PCIe adapters (molex is a rectangular/usually translucent plastic 4-pin connector roughly 1.25"/3cm wide) Doing this, make sure each adapter is connected to a separate Molex cable as it comes out of the power supply, not just two connectors on the same cable.

--320 watts should be enough to just squeak by on power, although it will place nearly 100% load on the PSU while gaming which could quickly burn out the unit or render your computer inoperable due to insufficient power. Also, the included power supply is probably not of the highest quality, making this endeavor even more dangerous.

OR

2. Buy a new PSU. I would highly recommend this one: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
