It may look pretty, but does it perform as well as it looks?

Many cheaply made power supplies tout high numbers for its wattage but at the end of the day just can't put out what they say they can.  Does the X-Finity have this problem?  After testing, it seems the numbers posted on the Ultra Products website are correct.  This PSU does, in fact, put out the power it says it does.

Proposed numbers, as per the Ultra website.

The voltages varied slightly during testing, but since they stayed within a nice range of about 2-3% all is well.   After confirming my test reports, I proceeded to plug in all of my extra parts to see how well it could handle a higher load.

Before:

  • Athlon64 3500+
  • ASUS A8N-E SLI
  • nVidia Geforce 7800GTX
  • 160gb SATA harddrive
  • 16x DVD-RW
  • 3 120mm Case Fans set on Medium
  • 2gb DDR400 ram
  • 19'' LCD Monitor

After:

  •  Athlon64 3500+ OC'd to 2.6ghz
  • ASUS A8N-E SLI
  • 2 x nVidia Geforce 7950GTX SLI
  • 160gb SATA
  • 120gb SATA
  • 200gb PATA
  • 120gb PATA
  • 16x DVD-RW
  • 52x CD-RW
  • 3 120mm Case Fans set on High
  • 2gb DDR400 ram
  • Printer
  • 2 512mb USB Thumb Drives
  • USB Cell Phone Charger, Charging my cellphone
  • 19'' LCD Monitor
Even after overclocking several components and plugging in every possible item into it, it still ran like a champ.  Never a shift in power or a drop in voltage.  The unit was as stable as a rock with everything I had and could borrow thrown at it.



Highs
Very powerful and reliable, looks much nicer than most PSU's.

Lows
A bit loud at peak performance.

Final verdict
An excellent, if expensive, purchase for any gamer.
