The Ultra X-Pro 600W EE is the next PSU to face [H]ard|OCP’s electrical obstacle course.  With an 85% efficiency sticker (at 300W load), and a 135mm fan it does fit the bill as an energy efficient PSU.  It’s 600W total may be why it has an odd classification at SLIZone when it comes to powering an SLI setup.  Find out what happened when [H] stressed it out (though it’s not as nifty as what Lee did to the Miller Electric).
“This Ultra PSU falls into a category that is drawing more and more attention now days, that being the “Energy Efficient” niche. Can 600 watts of power really be EE, quiet, and powerful all at the same time? Is it worthy of your custom system?”
