The Clever Power is an interesting mix of past and present styles. The glowing
orange power switch is a throwback to the time when the home computer industry
was dominated by electronics geeks and computers were bought in kits at hobby
shops. The AC pass-through is also an old idea; power supplies for computer
terminals often included an outlet for the monitor. On the other hand, the polished
chrome finish is strictly a fashion statement, which dates this PSU to our modern
era in which power supplies can make fashion statements. Of course, the most
interesting parts of the power supply are under the casing. Let's take a look...
The blower on the right is the reason why the vents can be so small without
compromising airflow. (NOTE: The red wire running out the exhaust vent was added by
us for testing purposes -- fan voltage monitoring.)
The positioning of the intake grill against the heatsinks is
an attempt to manage airflow within the power supply.
The size and location of the vent holes on the Clever Power are
unusual enough to warrant a second look. Clever Power appears to be trying
to direct airflow rather than just force as much air as possible through
the case. To this end, there are three possible sources of airflow: The main
intake through the back and two small intakes near the bottom middle of each
side. This arrangement guarantees a direct airflow path across the heatsinks,
with auxiliary cooling provided by the two side vents.
Clever Power's patented blower-style fan.
Unlike most power supplies, the Clever Power uses negative pressure airflow
to suck air through the unit rather than blow it
into the power supply.
The result is that the exhaust air is focused, meaning that the exhaust
vent need only be as large as the mouth of the fan.
The focused airflow that Clever Power utilizes is made possible
by the use of a fan that sucks air through the power supply along specific paths
rather than simply blowing it in and letting it find its own exhaust route.
This means that the components that are directly in the path of the airflow
will be better cooled than usual, while the rest of the power supply will have
less airflow overall. Hopefully the design engineers have paid enough attention
to design to place the hottest components in the airflow. Ultimately, the best
test of this will be how stable the unit is under a high power (and thus high
heat) stress test.
CABLES AND CONNECTORS
There are a total of six cable sets.
Only the cable for the ATX connector has a sleeve.
With the exception of the main ATX header, the cables are both
unsleeved and untwisted. This allows the individual wires to become tangled
quite easily; not good for cable management.
The individual wires are tangled even as they leave the housing of the
Another issue related to cables is that no 20-24 pin adaptor is included, so some of the latest motherboards will not be fully supported by the Clever Power. There is also no 6-pin auxiliary cable or any support for PCI Express. Because the Clever Power conforms to an older version (1.3) of the ATX12V standard, it is designed for higher on the 5V and 3.3V lines than is normal for the most recent motherboards.
The practical consequence of this is that the Clever Power is well suited for use in a system in which the processor draws primarily off the 5V line, such as an Athlon XP. The 12V line capacity of 20A is quite good, however, and it should also do well with more modern processors such as the Pentium 4 and the Athlon 64.
