I did some research myself and dismissed the two OCZs.
For what reason? I'm in need of a new psu, and thinking I may aswell buy something around 600W+ to make sure I have more than enough juice for a quad and a 5870 when they come out.
I've been checking out the OCZ ModXstream 700W, it has good reviews from what I have seen, a decent spec and is a fair bit cheaper than the Corsairs/Be Quiets.
Am I missing any obvious downsides of the OCZ, I may have missed something since I'm a little out of the hardware loop at the moment!
