Below is our system configuration we had used for testing the Ultra Products X-Finity 500W ULT31843 power supply.

Hardware Components
Processor: Intel Pentium D 820
Motherboard: Abit AW9D (i975X)
Memory: 2 x 1GB Mushkin DDR2-800
Graphics Card: ATI Radeon X1800XT 256MB
Hard Drives: Seagate Barracuda 7200.9 300GB
Optical Drives: Sony DVD-RW
Power Supply: Ultra Products X-Finity 500W
Software Components
Operating System: Fedora Core 6

Ultra Products advertises the X-Finity as being a "low-noise" solution, and as we found out in our tests, the power supply is indeed very quiet. Following our standard power supply tests, our idle results were recorded after the system was idling within GNOME for 30 minutes and all power management features were disabled. The load testing came after running Doom 3 and CPU Burn-In v1.00 for 30 minutes. Voltages were measured using a calibrated digital multimeter.


While not 100% perfect, we were surprised to see the gains that were made by Ultra Products based upon their past experience. While the voltages were very close to their theoretical voltages, once we had begun overclocking the systems the numbers had begun to fluctuate. Likewise, when loading up additional hardware components, a greater strain will be put against the power supply. Another area we were surprised to see with the X-Finity 500W was how quiet the power supply truly was during operation. The 135mm fan was relatively quiet while pushing a fair amount of air. At first we were also skeptical of the FlexForce cabling but in the end we were surprised to see how easy the cables would conform to our movements. While we still would not recommend Ultra Products for those building a high-end system, this company has improved somewhat if you are after something a little less powerful. At the time of publishing, the Ultra Products X-Finity 500W ULT31843 can be found for approximately $120 USD.
