Bigbruin.com has posted a review on the Ultra Products X-Connect 2 550W PSU

One of the latest Ultra Products brand power supplies is the X-Connect 2, also known as the X2. This power supply is only available in a titanium finish and with a total power rating of 550 Watts. The updates on this power supply from the previous generation include a modular FlexForce cable system and Dual Rail Technology. I will look at these items, among other things, to see how they enhance the power supply, and whether they are worthy updates.
