Bigbruin.com posted a review on the Ultra Products 2nd Generation X-Finity 600W PSU

Compared to the previous generation 600W X-Finity PSU, the second is a nice improvement. I have been taxing the first generation unit with all of the daily tasks I perform on my main PC since that review was published. The voltage rails are still rock solid, and I expect the same (or better) from the second generation unit with its improved specifications and addition of a second 12V rail.
