Ultra X-Pro & X-Finity 800watt Power Supplies


Testing Continued

The fans in both PSUs are barely audible. They are dead silent even at load!

After Spin Technology
I love this feature! After turning off my computer, my CPU and fans continue to spin for exactly five minutes at very low RPMs. I feel more comfortable with this and foresee this technology becoming standard in the computer industry!

I ran both power supplies at full load, each for 3 days straight. Of course, nothing 'bad' happened, no voltage spikes, crashes, or any sort of problem. Nice!


These PSUs are simply awesome! They are extremely sturdy and heavy and just scream "monster"! It ran everything I threw at it without a hitch and the brushed aluminium gives it a great look. Both are silent and the AST was simply awesome! For the X-Pro, I loved the sleeved cables!

On the negative side, the black paint on the X-Finity scratches extremely easily, so watch out for that. In my opinion, the Flex-Force cables on the X-Finity didn't do much and looks silly to me. It would have been nice if Ultra could have incorporated more connectors, especially SATA and PCI-E! Also, if you have a four pin CPU fan connection, then you will not be able to use the AST. The length of the unit threw me off as well. Overall, good PSUs. 9/10!
