Introduction and Features

The new Ultra X3 is a solid, high output power supply that offers quiet operation, comes with a full assortment of modular cables, and is backed by Ultra’s lifetime warranty.

Ultra Products has a well-earned reputation with PC enthusiasts for providing a full range of aftermarket components and accessories.  Ultra continues to expand their PC power supply line and we have their new X3 1,000W power supply in for review.  The Ultra X3 combines features from both the high-efficiency X-Pro EE 600W and the workstation/server class X-Finity 800W power supplies that we reviewed earlier this year.   The X3 features 1kW output capacity, Active PFC, high efficiency, quiet operation, and it is backed by Ultra’s Lifetime Warranty.

Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test.  Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage.  Our current suite of tests includes:

 

  • DC Load Regulation
  • DC Line Regulation
  • DC Cross-load (unbalanced load)
  • AC Ripple and Noise
  • Power Factor
  • Efficiency
  • Differential Temperature
  • Noise
  • Size and Weight
