I figured as much, but figured I'd ask over here because this community seems to be the most helpful. I've lurked around here, but this is my first post.
I did buy a 650w PSU. I went to Comp USA and they were out of the 450w that was advertised. However; I couldn't get the darn thing to work, so I put the 250w back in and it fired right up. I'll take it back next week and see if I can get a 450w modular... it's really what I wanted anyway. I just couldn't resist a sale...lol.
Again... Thanks for the help.
