It’s hard to find someone who can fully utilize a 1Kw power supply, while 800W seems to be a sweet spot for most high-end rigs. We are taking a look at two such power supplies from Ultra, the X-Finity and X-Pro.

Introduction


Just last week, we took a look at a rather powerful power supply in the form of the Tagan Silver Power SP-1000W. In the review, we loaded up the rails with as many drives and peripherals as we could and all the while, we monitored the rails with our trusty multimeter.

As interesting that is was, we ultimately came to the conclusion that while a 1Kw power supply was incredible to have in your PC, virtually everyone but the most hard core gamer will not need something this powerful. Taking a slight step down the power ladder, we are now taking a look at a pair of power supplies from Ultra, the X-Pro and X-Finity 800W. While the Ultras lack the extra 200 Watts of the Tagan, they are still more than most will need in the immediate future.

Ultra isn’t a stranger to anyone who has researched power supplies anytime in the past few years. Bursting onto the scene with their Ultra-X modular power supplies, the quickly made a name for themselves with the then new idea of allowing the user to pick and choose which cables the wanted to use and which ones they didn’t. While the pair we are looking at today lack the modular design, they do offer plenty of connections and each come armed with a different approach to keeping the cables in order.

In our Silver Power review, we attempted, at the very least, to hook as many devices as we could to the power supply and run it all out. While I am sure we never approached 1000W, I am confident that we can get reasonably close to the 800W that the Ultras provide.

On paper, both of these power supplies appear to be identical in all but appearance. As we will get into further later on in the review, the only thing that separates the X-Pro from the X-Finity is the cabling. The color of the aluminum housing is clearly different, with the X-Pro being silver and the X-Finity being black, but the main feature of each one is the cables and their covering.

The X-Pro comes shipped with the standard net sleeving while the X-Finity is coated with a silver silicon material to not only cut down on the width of the cables, but also allow a smooth surface for air to flow around inside a cramped PC case.

Packaging and the Unit

Coming in a package that loudly screams Ultra, the pair of power supplies are easily identifiable. The most striking piece of the box is the golden star sticker that brings to our attention that the power supplies come with a factory limited lifetime warranty. This is something that Ultra has done for quite a while now and is very much appreciated. Along with the SLi endorsement, we intend to see what else the pair has to offer.

Once we have the power supplies out of their packaging, looking at the two side by side confirms our hunch that they are identical power supplies with only their cabling to separate them… well, that and their blatantly different colors. Coloring aside, they both offer the same amount of connections, a pair of 80mm fans to move air across the warm components and identical power specs.

For purpose of not only time, but also space, from here on out all internal and external pictures of the units will be of the silver X-Pro power supply.
