PSU Features:

The X3 PSU has a long list of features and information that are pulled for the Ultra site and quoted below for you.

Ultra pulls out all of the stops for their latest power supply. By combining our "EE" (Energy Efficient) platform, which converts as much as 85% of AC power into DC power during typical loads, with a quiet 135MM ball bearing fan, our patented modular interface and our Limited Lifetime Warranty, Ultra clearly dominates the market with the new X3 power supply!

The X3 is super efficient, using less electricity than other power supplies when providing power to your computer and it generates less heat. Cooling is substantial yet silent by utilizing a thermostatically controlled 135MM ball bearing fan and a honeycomb cut exhaust grill. The X3 also has full range active PFC, which improves apparent power used by the computer. The modular interface allows you to only plug in the cables you actually require for your particular PC. The X3 is ready for even the most high end gaming rigs by providing up to four 6-pin PCI-e connectors, and the 800W and 1000W models provide the newest 8-pin PCI-e connector for the latest 300W graphics cards.

If you're looking for an efficient, quiet, powerful, modular power supply with a Lifetime Warranty, there's no reason to look any farther than the Ultra X3!




PSU Specs:

Truth be told, the list of features is pretty impressive, and it looks good so far.  Let's take a look at the specs of this PSU to see if Ultra can keep the ball rolling.   The first image comes from the PSU itself and is a close-up shot of the label.

According to the sticker on the PSU, this unit can product a total of 840W on the 12v line and 160W on both the 5v and 3.3v lines for a total of 1000W.  If we do a little math though, we see that the 5v and 3.3v lines should be able to produce more power than the sticker says.  A 5v line with a 28A rating should be able to deliver 140W, while a 3.3v line at 24A should deliver 79.2W of power.  That adds up to 219.2W - not the 160W on the sticker.  At 100% efficiency, this unit could provide around 1090W to your system - in an ideal scenario of course.

Speaking of efficiency, this PSU is rated as an Energy Efficient unit and according to Ultra, this is how it's efficiency vs. load breaks down.

Efficiency Graph


Although it's rated as Energy Efficient and 85% efficient at Typical load, in now way above do we see the PSU doing better than 80%.


It seems that somewhere the information hasn't gotten updated correctly.
