XPS 410 GPU Upgrade Question?

Kind of a noob question. I am getting a new GPU for my XPS 410 that I bought back last December. I was looking in the $200ish range since I am trying to save up for parts for a new gaming rig I want to put together, and don't want to break the bank. I do however want something that can keep up with todays games until I put my new rig together. I was thinking about this: EVGA 512-P2-N773-AR GeForce 8600GTS 512MB 128-bit GDDR3 PCI Express x16 HDCP Ready SLI Supported Video Card. I was wondering if I can install this puppy without having to mess around with acquiring extra power connections and jazz. I've recently looked inside when installing a RAM upgrade, but TBH I am not 100% sure what I should be looking for in that regard. I know what slot type it goes into. In it's system reqs it says it needs one 6-pin PCI Express supplementary power connectors or Two 4-pin Molex supplementary power connectors, and I'm not sure if either of those are there. Any advise would be appreciated!
