Ultra Products 2nd Generation X-Finity 600W PSU

**Doctor Feelgood**

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. - The Review

Review should have pointed out that the "TF" combined watts output for the +3.3V and +5V rails is extremely low for a PSU of this capacity.

TF=165Watts is LESS than many 300W and 400W "Total Watts" category units, which often provide a TF of 180Watts or more. High capacity PSUs with TF > 220Watts are available. Those extra 60+ watts can make a big difference in some configurations.

In system configurations with high power demand +3.3V and +5V components, users can run into power stability, random system freezes, undetected data corruption, and shutdown/reboot issues.

While a multimeter can provide some information, a storage oscilloscope provides information needed to assess voltage stability, and transient spikes and dips...particularly during instances of transient load variations.

Reviewers also need to start addressing electrical safety certifications, and verify a unit is actually safety certified as a power supply and doesn't just have a sticker based on a component grade (a misdirection method used by some manufacturers)
