HD6870 Installation problems, is my power supply good enough?

Recently I ordered XFX HD6870 after my 8800GTS 512mb died. I have a Corsair HX520W. I didn't expect installation to be so different. Apparently I have install with 2 power connectors unlike the only 1 for my 8800GTS.

I compared power consumption of both cards on the internet. 8800 is approximately 151 idle and 249 3D. The HD 6870 107 idle and 274 3D. I figured thats a small difference and my PSU is good quality. But I have no idea how to install 2 power connectors. I don't think I even have those. 8800GTS was installed much differently and thats how I always installed my gfx cards.

Any help here is greatly apreciated.

Edit: I can take some pictures if necessary

Your power supply is fine, just like my HX620 the HX520 has 2 PCI-E power connectors. Simply plug them both into your new 6870. Since you weren't using the second power connector, it's probably still in the box or somewhere.

I was just getting misinformed by the instruction manual. They're trying to sell me a ''high power'' gaming Power Supply.

Gonna test some bench marks on it :D Thnx for reply!
