Looking Inside

The X-Finity isn't built by Youngyear like the X-Connect.  Upon close inspection of the PCB and components and then running the UL number, we can tell that this power supply is built by Wintech.

Here's the Ultra X-Connect (left) sitting next to a X-Finity (right.)
The component values and layout are nearly identical, but because of the different Chinese manufacturers behind each unit, the colors of the components are different (different manufacturers used)
and the heat sinks are of a slightly different design, albeit approximately the same shape and size. Note the power switch and AC input are reversed.

Despite similar placement and size of some of the components between the X-Finity and X-Connect, the values are still a little off between the two power supplies. This is probably why the end result is a power supply that can allow for "only" 28A (the X-finity) versus 34A (the X-Connect) on the 12V rail, 32A versus 28A on the 5V, 20A versus 28A on the 3.3V rail, etc. (you'll get to see all of the specs in a little bit.)

The heatsinks in the X-Finity, although different in design than the X-Connect, are still smaller than most.  Once again, the power supply seemed to run a little warm and the fans spun up. I may be wrong, and I'm sure the heatsinks are adequate for this power supply, but I think the fans wouldn't need to spin as fast if the heat sinks were a little bit larger.

Here's the inside of the Ultra X-Finity 500W.
