Ultra Products X-Finity 500W PSU with Active PFC
August 30, 2006

A good number of Ultra Products brand power supplies have been reviewed at over the last few years, and they have all shared a few things in common... Respectable performance and outrageous designs that are sure to grab attention. Featuring things like chromed housings, LED fans, acrylic windows, and silver cables, the previous Ultra Products power supplies seemed to be about appearances as much as they were about performance.

The latest power supply from Ultra Products to land on the test bench at turns its back on the over-the-top, eye-catching appearance of its predecessors, while also improving upon the performance characteristics.

The Ultra Products X-Finity 500W PSU with Active PFC to be covered in this review can be distinguished by more than just Active PFC over previous X-Finity units. It has lost the chrome finish, there are no LED fans, there are no acrylic windows, but it can easily be identified as an Ultra Products X-Finity unit due to the silver FlexForce cables. In addition, the housing now sports a rather dull black finish, but it is aluminum instead of steel, and the single 120mm fan has been upgraded to 135mm.

I am actually quite fond of the appearance of this version of X-Finity, and if a power supply could be considered mean looking, this one would be what I might picture. If you prefer the style of the other X-Finity power supplies, don't worry, Ultra Products is still producing them, too!

Before jumping into the review, let's take a look at some published data on the Ultra Products X-Finity 500W PSU with Active PFC.


» FlexForce Cables
» Dual Rail Technology:
   » Better Power Distibution - Dual Rail Technology distributes power to components that require it the most.
   » Dedicated CPU Rail - Dedicated 12V Rail for the 2x2 Motherboard Connector
   » More power where you need it
» Supports AMD and Intel Motherboards
» Low Acoustic Noise
» 135mm Fan
» Meets ATX Version 2.2, v1.3, and ATX 12V Version 2.2 Specifications
» Short Circuit Protection
» In-Rush Current Protection
» Thermal Overload Cutoff Protection
» MTBF > 100,000 Hours at Full Load, 110VAC and 25°C Ambient Condition
» FCC and UL Recognized


» DC Output:
   » +5V@30A
   » +3.3V@30A
   » +12V1@16A
   » +12V2@18A
   » -12@0.6A
   » +5VSB@2.5A
» Total Output Power: 500W (Full Load, Nominal Input Voltage)
» Efficiency: 70% Typical at Full Load and Nominal Input Voltage
» AC Input:
   » AC Input Voltage: 115V/230V
   » AC Input Frequency: 50-60Hz

From the data above we see that you get decent voltage ratings on the key rails. The two 12V rails are not symmetrical (one is 16A and one is 18A) and they combine to provide a maximum power of 384W. The 3.3V and 5V rails combine for 160W.
