I've read a few reviews on the 620 watt model and it looks to be a real winner. They use 105 C rated Japanese caps throughout and they also rate their power at 50 C, just like PC Power & Cooling does. I also like the idea that several of the cables are removable too, so if you don't need the extra connectors you can leave them out of your case and out the way. I've added them to my short list of psu's to get when shopping. They also have a 5 year warrantee too.
