CM PSU's are a grab bag of caps, while occasionally you'll get something decent, usually it's a POS.
Seems to me that the CM one seems to work great though? So does mine that i currently have. Plus, this one is 800w, Gold certified, and modular. ? And ive never heard of Leda, and doesnt seem to get good reviews. Neither does the XFX one. Might get a corsair one, but want to keep price down as much as possible.
