Bottom Line:
The Ultra X-Finity 500W has no modular cables, UV windows or UV lights, but it does have a high rated 12V rail. SLCentral put it through its paces, how did it cope when loaded up significantly?

Outcome and Results
What's my opinion about what the outcome will be?
Although
a 500W power supply and bearing the same "Ultra" brand
name as the X-Connect, I don't think we'll see the exact same results. The
5V is higher, and the 12V is lower, but still they both show strong numbers.
This power
supply lacks a lot of the luster some of the other power supplies I've tested
have shown. With only a shiny finish to save
it's "feature score," this power supply better perform if it's going
to get a decent grade!
Let's
take a look at the test results:
As
usual, red means the power supply is out of spec.
