When it comes to
brand recognition in the PC power supply market, PC Power and Cooling is
the geek equivalent of Ferrari. The Turbo-Cool series have been
chosen for the illustrious honor of powering the MaximumPC Dream Machine
on a regular basis, and their quality is known throughout the enthusiast
community. However, the top end of the PSU market is not
nearly as elusive as it used to be. New market contenders like
Corsair, Ultra and Antec have all launched products intended to assault
the top position. Does PC Power and Cooling retain their elite
status, or have they been overtaken? Today, we will find out by
comparing the Silencer 610 EPS12V with my current standby, the Corsair
620HX.
Out of Box Experience:

First off, let's take a look at what we have.
Unlike motherboards and video cards, PSU package bundles rarely have
much in the way of extras, and that is just fine by me.
Here we have the power cable, the PSU, four screws and a basic
manual.

For the PSU unit itself, the first thing we
notice is the fan configuration. Instead of a 120mm fan on the
bottom that many PSUs today use, the Silencer uses a single 80mm fan
directly on the exhaust. Everybody knows that the larger fan
you use, the less RPMs required to push the same CFM, and thus less
noise generated. So, how does PC Power and Cooling justify
using a smaller fan on a "silent" power supply? According to a
PDF found
here, PCP&C claim that the secret is in fan layout. PCP&C
goes on to state that the Silencer reduces "air turbulence" by
making the supply a little bit longer, and saving some space right
in front of the fan. In another document, entitled
"Power Supply Myths Exposed!", PCP&C goes on to claim that power
supplies with a top mounted 120mm fan generally skimp on everything
from passive cooling within the unit, to smaller capacitors and
other components that essentially limit the power capabilities of
the supply, in order to allow for the space for the large fan.
We will investigate these claims further as we go on.

As we rotate the PSU around, we get a further
feel for the aesthetic feel of the unit. The entire supply is
textured in a subtle black. We can also see the "SLI Ready"
sticker.

On the other side, we see a little venting, and a
sneak preview of some of the coils.

Nothing terribly exciting here, just the top of
the PSU.

On the front of PSU, we see the rest of the
cooling, in the form of vents. This should be where most of
the fresh air is pulled from.

On most PSUs, a fan would be installed here,
however, on the Silencer, all we have is the power ratings label.
Shall we crack her open?

With the top removed. we see what
PCP&C were referring to in regards to giving the fan some breathing
room. The large passive heatsinks are also aligned in
such a way as to be the most conducive to airflow. The
large vents can be seen on the right, this is where the fresh air
comes from.

Here we have a close look at the coils. A
small plastic guard ensures that the coils do not make contact with
the casing.

On this side, we can see some of the caps, as
well as the wiring configuration. While it appears the 12V
(yellow) rails are split into two rails, it is actually a single
unified rail.
