Ultra. The name says it all. Here's a company that's obviously targeting high
end gamers. With everything from cooling fans, to cases, to heatsinks, they've
got all the "extras" of the enthusiast's system covered. The reviews
listed on Ultra's web site come from such sites as 3dgameman and OverclockersOnline,
sites that are into performance only and don't take low noise into consideration
when reviewing products.
A year ago, we reviewed a 500W sample of the
Ultra X-fininity, the company's first series of PSUs. Our conclusions were
that beneath its glossy surface, the unit's electrical performance was average,
and it was far too noisy for us to consider seriously. Ultra's marketing folks
claim the new X-Pro is better in every way, including its acoustics. So we agreed
to give test out a couple of 600W samples.
No fancy extras inside the box.
FEATURE HIGHLIGHTS AND SPECIFICATIONS
The Ultra X-pro offers a number of high end features, such as
active PFC, high efficiency, and sleeved cables.

| FEATURE & BRIEF |
COMMENT |

Meets ATX Version 2.03, and ATX12V Version 2.2 Specifications
|
A must have these days. |

We'd hope this is true for all PSUs today. |
| Sleeved cables. |
Good for airflow. |
| Short Circuit and In-Rush
Current Protection |
Good for your system. |
| MTBF > 100,000 Hours at Full Load,
110VAC and 25°C Ambient Condition |
MTBF isn't really the
greatest measure of reliability, since it depends on many factors. |
| FCC and UL Recognized |
Hmm... Approved would be nicer to see. |
| Three year warranty. |
Good. |
| 100-240V Automatic full range AC Input |
Good. |

Editor's Note: There is no claim about multiple independent 12V
lines, just a single 12V line rated at a whopping 36A, which is refreshing to
see. The only thing "independent" about 99.9% of "multiple"
12V lines is that there may be more than one current limiter in the circuit,
but the 12V source goes back to the same single transformer.
