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

FEATURE & BRIEF COMMENT
Meets ATX Version 2.03, and ATX12V Version 2.2 Specifications
A must have these days.
Supports AMD and Intel Motherboards 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.
78% Efficiency at Full Load, Nominal Input Voltage Not bad for 600W output

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.
