I thought of contacting the seller, but they didn't appear too knowledgable through their communication, and besides it wasn't a lot of cash that I feel it's worth that hassle. I haven't done any more trouble-shooting on it, though I did use an online PS calculator, and with that particular mobo/chipset, that card, and more devices than I have hooked up, I came in at about 320 watts usage. My PS is 380 watts. I'll consider the suggestion. As well, I know someone who may test it for me further, though.
