PC Apex has posted a review on the Ultra Products X-Connect 2 550W Power Supply

The improvement on the cables this time around was the switch to Flex Force cables. They are still UV reactive with each wire being independently coated. Since the cables consist of individually wraped wires, the cables themselves are thinner and are easy to fold-over, tuck behind, and even run under the motherboard. Even though this might not be appealing to everyone it still adds a WOW factor to laying out the wires in a system. This is a much needed improvement over the first gen cables that were kinda stiff and round which made it difficult to route them in tight spaces.
