This is one I'm looking at. Several experts have suggested that I need a new PSU because the one I'm running now is barely adequate to for my system (basics AMD Dual Core CPU, dual Geforce 7900 gt cards in SLI, 3GB ram and do a lot of video editing. I was concerned at first becuase system was already running hot. However, I have installed 3 fans (one in front brings air in over my boot HD, attached fans to second HD and then rear fan between GPU cards out the back. System now runs in the mid 40s C when playing games, video editing mutlitasking etc. The other concern is that I have to keep it in a cabinet because I have 5 kids 7 and younger two of which are busy 1 year old twins. So airflow from the front is not great but the fans blowing out the side are okay and the back is open so temp seems to be okay for now. I still don't think I need much more power or I'm going be back in the same boat again with high temps. Anyway, this one has more power, SLI certified and comments say quiet (which I'll get into in a second).
So that is the one I'm looking at but considering changing the fan on it. I'm also considering changing the other fans. I bought cheap ones to see if they would help. They did but my system sounds like a freight train when it's running. I may just have to live with that considering my placement limitations. But if anybody is interested I'll post another thread to discuss the best (most quiet and efficient) fans for HDs, CPUs and PSU.
