Internally the X2 is very
nicely laid out with all of the wire wrapped
and tucked so as not to leave a rat's nest
appearance. The unit also has two
large size filter capacitors which will help
filter the AC voltage out as the power
supply works to convert the voltage into the
useable DC voltages that our computer will
need. A pair of large heatsinks are
centrally located in the unit and serve to
remove the heat away from the transistors
and regulators used in the X2.
If the fan used in the X2
follows the same standards as the other
120mm UV Translucent Fans the
speed on it will be 1700 RPM,
Air Flow:
64 CFM,
Noise:
29.78 dBA and draws at
total of 3.6 watts.
The three programs I
have chosen to use to test the Ultra X2
are all programs that have the ability
to stress the system and the power
to the max.
Winstress from our friends at
Ultra-X Incorporated uses advanced
simulation means whereby you can stress
test the overall performance and
stability of a computer under normal and
excessive loads to ensure that critical
information and services are available
at speeds your customers expect.
S & M is just what the name
implies it will literally beat your
machine up, this is a small program from
a Russian developer that works both your
processor and your memory, plus it has
the feature of being able to monitor key
voltage rails as you conduct your tests.
The last program need no introduction
and that is Sisoft Sandra's Burnin
Wizard, this may be one of the most
popular software programs for stressing
testing systems available.
The test will be ran in two stages, the
first will simply involve installing the
power supply and starting the computer
and allowing it to idle for 1 hour to
establish a baseline voltage reading for
all of our test points.
All voltages were recorded using a Sper
Scientific Datalogging Multimeter using
the high / low feature on the unit.
All voltage measurements were taken from
a cable end so that we could see if
there was any apparent lose of voltage
due to the plug-in connections.
That is the one drawback with modular
power supplies, unless the connection as
absolutely rock solid you have a chance
to add resistance into the the line and
thereby dropping the supplied voltage to
whatever device it might be plugged
into.

The voltages we recorded were just about as good as you can get with any power supply on the market today so I think it is safe to say the Ultra X2 kicks some major ass when it comes to handling a heavy duty stress test. We were a bit curious to see if the X2 would be as stable if overclocked the system a bit so we clocked the processor up to 3.7 GHZ and ran another stress test and the result were almost identical to the first one we ran. So I am completely satisfied that this really is a beast of a power supply and that Ultra really did get one right on the mark!
Plus you can see by the pictures it looks pretty damn sweet once it is fired up inside the case. So what is the price on this supply you might be wondering, it retails for $129.00 which for the power your getting and the stability is an excellent buy especially in light of some of the prices of other power supplies that are selling for $40.00 to $60.00 more and don't offer anymore features or provide any better stability.
