Ultra X-Finity and X-Pro: Two 800W PSU for Your SLI Needs

Introduction

If you just recently purchased the latest GeForce 8800 GTS/GTX graphics card, you may found out that your power supply is just not up to the task to handle such monster card.   Often, not only a poorly constructed power supply will not deliver the needed wattage to the components, it could potential damage them as well.  The power supply is the heart of the system and it cannot be overlooked specially if you have expensive components, such as GeForce 8800.
 
The power supply market has never been more vibrant than ever and the quality seems to be getting better and better.  With the release of SLI/Crossfire and the emerging market of quad core, almost all computer systems would benefit from having a beefy power supply that can take the load and have enough juice for future upgrades.  Ultra has entered the market of high end power supply like the rest of the industry.  They have just released not one but two new power supplies rated 800W: the X-Finity and X-Pro and they are kind enough to send both of them to us for a review.

The company

Ultra has been in the computer business for quite awhile now.  They offer a wide range of products, such as: case fans and lights, CPU designer cases, DVD products, hard drive coolers, media drives, complete memory solutions, memory coolers and power supplies.  I think what makes Ultra stands out is their warranty policy.  They are so confident in their products that “all Ultra Power Supplies and Cases now carry a three year warranty that they will be free from defects in materials or workmanship. In addition, that warranty is upgradable to a LIFETIME warranty by simply registering online. Additionally, all [their] other products carry a one-year warranty which is also upgradable to a three year warranty.”  It’s almost unheard of in the computer industry to carry a lifetime warranty on a power supply.
