Ultra X-Finity 800W PSU Action Review

Posted on 2007-04-09 17:07:54 by Thomas De Maesschalck

We have taken a look at the Ultra X-Finity 800W PSU and tested this unit to find out if it has the stability, performance, cable management and quietness that we've all come to expect out of good power supplies. The MSRP is $200USD on this unit so it should be a good unit. We'll take a look in the review to see how it performs, but reliablity can only be determined with time. A lifetime warranty takes away the risk though.

Voltage drop is virtually non-existent. The 3.3v line dropped 0.01v under load, while the +5v line dropped 0.05 volts. All of the +12v lines were very stable and the greatest drop was on the +12v4 line (PCIe) and that dropped 0.06v under load. That equates to less that .5% drop. That is incredibly stable. As far as noise goes, I can't hear this PSU over the other fans in the system at all.
