The Xclio 450BL was just also recommended as a low-medium end PSU on my favorite overclockers forum.
Apok if you could add the Xclio 450w model to low-medium that would be awesome....you don't have to but the Xclio Goodpower 500w is a good medium-high as well being about as stable the BL but with more amps and watts.
Still the 450BL is an awesome deal and I believe should go in there.
