Ultra X-Pro 600W EE Power Supply
 

Today’s Ultra offering is slightly different from the first Ultra unit we reviewed in that it has been tweaked to try and hit Ultra’s goal of 85% efficiency. Moreover, with the inclusion of a 135mm fan (the second largest I have seen on a PSU) it appears Ultra is aiming squarely for the quiet cooling demographic with the Ultra X-Pro 600W EE.
