SysOpt has posted a review on the Ultra X2 550W Modular Power Supply

Ultra has become a well-known brand by adding a few functional and many aesthetic features to what would otherwise be considered boring products. Aiming to please the largest possible group of buyers, Ultra has also kept its prices reasonable and warranties admirable. X2 represents the second generation of high-feature X-Connect Modular Power Supplies; can it deliver high-performance to match?
