How do I connect a powered home theater subwoofer to my computer's sound card? I was thinking about using a 3.5mm auxilary to RCA cable. Would I connect the 3.5mm aux. to the regular green jack on the sound card or would I use the orange center/sub jack?

Its just a regular one thats integrated into the motherboard. It has a green, black, orange, pink, and blue 3.5mm aux. jack.

The orange port on your motherboard is the Subwoofer and center channel output. Now how you go about connecting the sub you have to that I don't know. Not sure if you can....

I think using a headphone splitter for the green port will work. For one connection, it will be for the front left and right speakers. The other connection will go to the subwoofer.
