The Ultra X3 1000 Watt PSU - Up Close
Technology Overview

The Ultra X3 1000 Watt PSU is both functional and attractive.  The outer shell has a platinum mirrored finish that compliments its quality feel.  The end of the unit sports all of the required modular connections to marry up to the included cabling.  While each plug isn’t labeled, the series is unique, making it easy to discern which cable marries up to the appropriate output.

Total Output Power:
1000W (Full Load, Nominal Input Voltage)
Efficiency:
85% at Typical Load

Input
AC Input Voltage: 115V/230V

AC Input Frequency:
50-60Hz
AC Input Currents:
· 13A (RMS) for 115VAC input
· 8A (RMS) for 230VAC input

The Ultra X3 is rated for a total of 1000 watts of peak power.  The +5V and +3.3V outputs combine for 160W at 28 and 24 amperes respectively.  +12V power maxes out at 840W and 70 amperes while -12V and +5VSB outputs combine for 19.7W and 25W.

Cooling the Ultra X3 is an oversized 135mm ball-bearing fan that provides adequate airflow while maintaining low noise.  The rear of the unit is entirely perforated for reduced air resistance as well, and the fan speed is throttled based on temperature to help furhter control fan noise.  In our test environment, we found the PSU to be exceptionally quiet and could not detect any audible differences to coincide with fan speed fluctuations.  In the end, the Ultra X3 was virtually silent throughout testing.

One item worth mentioning is what Ultra dubs Flex-Force Technology, which is a fancy name for extremely flexible cables.  The cabling is the easiest to manipulate, most flexible cabling we've encountered in a PSU, with virtually no spring or memory to it at all.  The idea behind Flex-Force Technology is to be able to easily route the cables so they can be hidden for maximum airflow within a case.  After setting up this PSU in a test case, we found the cables to be the easiest we've had to work with to date.

This is a great PSU, I won mine on LR.  I haven't been able to use all of the juice, but so far it is great.  Modular design, not too much longer than a standard PSU (only about an inch longer than my old 305W PSU).

 Check this one out if you need a lot of power!

Normally, Ultra makes some pretty bad PSU's. But they do have a few which are outstanding...this is definitely one of them =D.

Here's a jonnyguru review for you guys ^_^...It's a beauty.

This is an awsome power supply. I have one myself, the only thing that I don't like about it that it is very loud. Compared to my other fans in the computer, only the power supply is making the noise in my computer. It kind of sucks.

Even the Ultra 700w modular is noisy.  Had to stick it in a heavy steel case to quiet it down.

I still see no need for a 1k Watta PSU......even with a quad-sli setup or something most rigs STILL wouldn't need that much power -- especially if the PSU is very efficiant which well, should be a MUST on anyone's list when getting a PSU.

 I heard Ultra used to make poor PSU's, but from what I have heard lately, they seem to be turning things around.

 

Actually a nice high-wattage (and amperage of course) PSU is one of the best things you could buy. Power consumption is only going to go up, and buying a 600 watt now, and an 800 or 900 later is just a poor investment.

 

Plus I love the security and future proofing knowing that it can handle any card I throw in it in the next year or so.

I still do not understand why people use 1KW power supplies for their workstations.Isn't a lot of power unused?

I wouldn't have bought this unless I needed all of the Wattage, though since I won the thing, I will use it.  I probably only use about 400W, but its not like the thing produces 1kw, then the other is wasted, it only produces enough watts to be used.

I had one of the original X-Connects for the longest time which ran great however and its good to see Ultra has been on track with the quality of their PSUs ever since they released their X3 lineup. As for the rest however not so much like their X2 lineup.
