Sorry, probably should've added that originally. The box says Corsair TX750M. I think the guy helping me at the store said it was one of the higher end ones they had, but I don't know if that is high enough quality.
Also, (figured I should add to this post while you guys are looking at it, rather than clutter up the forum with another) is a GPU fairly easy to install? I have no experience installing computer hardware, though I would love to learn, and would rather not have to leave my comp at Best Buy for a few days. Any suggestions?
