Ultra Products' original X-Connect power supply can be attributed with being the world's first retail ATX power supply with a fully modular cable design. This Ultra X-Connect power supply had also boasted a magnificent finish on the exterior, however, when it came to the performance this PSU was widely criticized. There are numerous horror stories of the X-Connect failing after a short lifespan and other problems associated with this product. Ultra Products though have taken their power supplies through a number of revisions since the first-generation X-Connect had shipped back in 2004. The last time we had a Ultra Products power supply in our facilities for testing was with the X-Finity 600W Titanium, and at that time the power supply had performed fairly well, but it certainly wasn't top-notch. Recently, however, Ultra Products had asked us if we would take a look at their new X-Finity 500W PSU. This new Ultra X-Finity boasts dual 12V rails, active PFC, NVIDIA SLI Ready, and more. In this review today we are checking out the X-Finity 500W ULT31843 to see if things have changed for Ultra Products.

Arriving at our doorstep was a very decorate X-Finity package. Displayed on the sides of the packaging were various shots of the product as well as listing the various features and specifications. The package also heavily highlighted that this product is NVIDIA SLI Ready and that Ultra Products offers a limited lifetime warranty. Other mentioned features were being low noise with a 135mm fan and that it uses active PFC. Opening up the packaging two blocks of Styrofoam had protected the power supply from incurring any possible damage.
