OCModShop posted a review on Ultra's X-Finity 500W PSU

The Ultra X-FinityT 500 Watt PSU w/ Active PFC appears to be exactly what one would look for in a power supply of this energy rating. First, it is in an attractive enclosure of black brushed aluminum, with well fitting seems, and strong-looking materials. It is also very heavy - lots of circuitry as work here. The cables are what Ultra calls, FlexForce: They are designed to make routing and space-management better inside your case. They are an attractive black and silver scheme, and much more pleasant to use than the standard red-black-black-yellow cables. Of particular interest is the huge 12cm fan, which spins relatively slowly, and is very quiet. Yes, I would certainly be proud to show off this power supply. But does it perform?
