When building a high performance
system quite possibly the most important choice
of component is the power supply. There is no
point in building your very own home made supercomputer
to have it powered by a low end supply that has
problems holding a good rail. Many users fall
foul of the misconception that “the higher
the wattage the better” where as others
feel they can save money on something they deem
as unimportant. When building our Driver Heaven
review systems we take time to look at the variety
of supplies and to decide whether they can take
the extreme load we have to throw at them when
reviewing the highest end hardware. When deciding
to build a gaming system based around the latest
array of hardware such as AM2 and Conroe with
either SLI or Crossfire delivering the graphics
it is extremely important to purchase a unit which
will ensure you end up with a stable system.
The Enermax Noisetaker
The Noisetaker comes packaged
in a box which surpasses expectations. Whether
looking for basic information on specifications
or detailed information on wattage/ampage the
Enermax box tells us everything we need to know.
We find the unit well protected
in bubble wrap and on top is the documentation.
The white box which is visible on the right contains
the power cord, 8-4pin converter, screws to install
in a case and an Enermax sticker. Basically everything
that is required is included and in addition the
manual is reasonably well written.
We have mentioned before
that it would be nice if Enermax put a little
more thought into the protection of their units
during shipping, as a layer of bubble wrap isn't
the best solution. Once opened we find the PSU
is a very attractive unit. The metallic blue paint
goes very well with the gold fan grills and creates
an initial feeling of quality. They say that first
impressions count, right?
The Noisetaker features
the now standard two fan design with one fan on
the base (clear) to suck air in and the other
to expel it out the back. Both fans are Silence
ball bearing branded models. Also shown above
is the power button and fan speed control. This
small dial allows you to adjust the fans for best
performance or more silent running. It has to
be said though that even at max RPM the PSU is
still very quiet.
At the rear we find the
cabling, this particular unit has everything the
end user is likely to need for some time. This
includes floppy connectors (2), standard molex
(7). 24 and 20 pin motherboard connectors, 8pin
12v power connector, sata drive connectors (4)
and PCIe graphics connectors (2). Also in the
bundle of cables is a fan speed connector which
caters for the monitoring of the fans via software
Inside the unit the layout
is clean with plenty of room for good airflow,
there are also no signs of low quality workmanship
or the use of cheap components.
Before we look at the performance,
lets take a few moments to study the specifications
(as stated by Enermax).
the board those are very impressive figures. Having
22A on both 12v rails should be more than enough
for all currently available video cards. There
is one final design aspect which the above table
and our pictures do not tell you and that is the
smart fan function Enermax have incorporated into
the unit. This technology works by running the
PSU fans for a short time (at least 30seconds)
after the system is turned off to ensure that
the internal components are cooled which should
(in theory) increase their lifespan. The temperature
level for shut down of the fans when in this state
is 40c or 104f.
