The BFG Tech EX-1000 1000W modular power supply is a quiet, well built unit that almost really impressed me. If I had tested in our old format I wouldn't have seen the ripple issues, and would have been left with the "semi-modular" design as my biggest beef. With all things considered, I would still recommend it, especially in situations where it wasn't to be used under a constant 1000W load.
