    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.

    Ultra X-Connect 500W Zero Load Test One (375W) Test Two (305W) Test Three (492W) Full Load (550W)
    12V 12.08 12.22 12.65 12.70 12.30
    5V 5.28 5.09 4.99 4.96 4.99
    3.3V 3.38 3.40 3.43 3.50 3.49
    Efficiency 36% 77% 76% 72% 72%
    Power Factor .55 .70 .68 .70 .69

    Temperature under load = 42C. Temperature after power off =52.1C.
