Final Thoughts and Conclusion


Ultra has been in the business of producing good looking products which are known to perform well, and still not cost a fortune. We recently reviewed the Ultra ULT33186 Chilltec TEC CPU Cooler, which offered a unique blend of technologies into one product. Equally as unique is the Ultra X-Pro 800W Aluminum PSU ULT33185, which matches a very attractive power supply chassis with high-performance electronics previously found in mission critical components. Offering 800 watts of power gives the X-Pro a very wide range of applications: from pedestal servers to hardcore gaming systems. Benchmark Reviews has seen plenty of power supplies that look good, and they often promise more than they deliver. Ultra's X-Pro 800W will need to prove that function still comes before fashion.

By combining the stability and durability of a server power supply with the sleek looks of a gaming power supply, Ultra once again addresses the needs of demanding, high end gaming systems. The X-Pro 800W can supply a continuous 660W across its four 12V rails. The X-Pro 800W features an anodized aluminum housing and cool black sleeved cables. The X-Pro 800W also features "After Spin Technology" to help quiet the system and aid in prolonging the life of your components. Connectors for chassis fans are thermostatically controlled; RPM's are reduced when temperatures inside the case are low. PSU, chassis and CPU fan connectors remain spinning several minutes after the PC is powered down allowing the system to gradually cool down after use. When you use the Ultra X-Pro 800W, you'll never again have to wonder if you'll have enough power to get you through the next level, or next CPU or GPU upgrade.

Regardless of the system or purpose there is a given rule: whether it is a simple workstation with integrated components or an advanced gaming system with the newest technology available, everything requires power to operate. As anyone who has suffered the failure of a low-end power supply will tell you: not all power supply units (PSU's) are created equal, and looks really don't mean a thing. With more connections and power than any modern computer should consume, we will do our best to offer perspective on the DC voltage regulation and AC current ripple.

Ultra X-Pro 800W Aluminum PSU ULT33185

Next generation platforms and high performance graphics cards are essential to modern gamers and hardware enthusiasts, just as much as the new software designed to use them. Offering two PCI-Express cables and a total of only four serial ATA connectors, the Ultra X-Pro 800W Aluminum PSU ULT33185 is built to provide sufficient output to power SLI sets with quad-core processors. With a sustained output of 800W over four +12V rails to provide uniform distribution of power, the Ultra X-Pro 800W Aluminum PSU ULT33185 is very capable of driving today's highest-end systems, but may not meet the needs of larger future configurations despite the power output.

Benchmark Reviews has seen some major changes within the power supply industry over the past year. Even in such a limited purpose industry, somehow fads manage to come into existence. At one point, the number of rails a PSU offered was key to media hype. At another point, you could see everyone pushing for the highest watts in their new product. I can't forget how modular power supplies, with the assortment of cables and interfaces, also shared some time in the limelight.

The latest trend seemed to be 80-Plus efficiency, but since most PSU's are at least this efficient the label has lost meaning. And then without any warning, it was as if every company manufacturing power supply units suddenly decided that they could win the battle for industry dominance by combining all of the above features, and add a nice paint job or mirror finish for good measure. The new generation of power supplies has begun to amp up the competition for placement in your computer case. Antec’s EarthWatts series was among the first to cause a stir in the PSU industry by emphasizing efficient power delivery over the multi-rail hype over two years ago. But now 80% or better efficiency is very common.

Somehow, the industry is shifting back to square one. The Ultra X-Pro 800W Aluminum PSU ULT33185 does not offer modular cable groups, and other manufacturers (such as Hiper) are following suit. The primary complaint is the failure rate of such units, which has caused manufacturers to receive higher returns for non-faulty products due to cable and connection issues.
